No, you are not maximizing your utility. To determine if utility is maximized, you need to compare the marginal rate of substitution (MRS) to the price ratio (Px/Py). In this case, the MRS is 4, but the price ratio is 4/2 = 2. Since MRS is not equal to the price ratio, you can improve your utility by adjusting your consumption.

To determine if you are maximizing your utility, you need to compare the marginal rate of substitution (MRS) to the price ratio (Px/Py). The MRS measures the amount of one good that a consumer is willing to give up to obtain an additional unit of the other good while keeping utility constant.

In this case, the MRS is given as 4, which means you are willing to give up 4 units of Good Y to obtain an additional unit of Good X while maintaining the same level of utility. However, the price ratio is Px/Py = $4/$2 = 2.

To maximize utility, the MRS should be equal to the price ratio. In this case, the MRS is higher than the price ratio, indicating that you value Good X more than the market price suggests. Therefore, you should consume less of Good X and more of Good Y to reach the point where the MRS is equal to the price ratio.

Since the MRS is 4 and the price ratio is 2, it implies that you are purchasing too much of Good X relative to Good Y. By decreasing your consumption of Good X and increasing your consumption of Good Y, you can align the MRS with the price ratio and achieve utility maximization.

The coordinates of point B on line segment AC are (8/13, 17/26).

To find the coordinates of point B on line segment AC, we need to use the given ratio of 2:12:12.

Calculate the difference in x-coordinates and y-coordinates between points A and C.
  - Difference in x-coordinates: -4 - 2 = -6
  - Difference in y-coordinates: 7 - (-8) = 15

Divide the difference in x-coordinates and y-coordinates by the sum of the ratios (2 + 12 + 12 = 26) to find the individual ratios.
  - x-ratio: -6 / 26 = -3 / 13
  - y-ratio: 15 / 26

Multiply the individual ratios by the corresponding ratio values to find the coordinates of point B.
  - x-coordinate of B: (2 - 3/13 * 6) = (2 - 18/13) = (26/13 - 18/13) = 8/13
  - y-coordinate of B: (-8 + 15/26 * 15) = (-8 + 225/26) = (-208/26 + 225/26) = 17/26

Therefore, the coordinates of point B on line segment AC are (8/13, 17/26).

The statement P(-3/2) is invalid since n must be an integer greater than or equal to zero. As a result, our mathematical induction is complete.

For each of integers n ≥ 0, let P(n) be the statement n × 2² = n × 2^(n+2) + 2.(a)

i. Writing P(0).When n = 0, we have:

P(0) is equivalent to 0 × 2² = 0 × 2^(0+2) + 2.

This reduces to: 0 = 2, which is not true.

ii. Determining whether P(0) is true.

The answer is no.

(b) Writing P(k). For some k ≥ 0, we have:

P(k): k × 2²

= k × 2^(k+2) + 2.

(c) Writing P(k+1).

Now, we have:

P(k+1): (k+1) × 2²

= (k+1) × 2^(k+1+2) + 2.

(d) Show by mathematical induction that P(n) is true. By mathematical induction, we must now demonstrate that P(n) is accurate for all n ≥ 0.

We have previously discovered that P(0) is incorrect. As a result, we begin our mathematical induction with n = 1. Since n = 1, we have:

P(1): 1 × 2² = 1 × 2^(1+2) + 2.This becomes 4 = 4 + 2, which is valid.

Inductive step:

Assume that P(n) is accurate for some n ≥ 1 (for an arbitrary but fixed value). In this way, we want to demonstrate that P(n+1) is also true. Now we must demonstrate:

P(n+1): (n+1) × 2² = (n+1) × 2^(n+3) + 2.

We will begin with the left-hand side (LHS) to show that this is true.

LHS = (n+1) × 2² [since we are considering P(n+1)]LHS = (n+1) × 4 [since 2² = 4]

LHS = 4n+4

We will now begin on the right-hand side (RHS).

RHS = (n+1) × 2^(n+3) + 2 [since we are considering P(n+1)]

RHS = (n+1) × 8 + 2 [since 2^(n+3) = 8]

RHS = 8n+10

The equation LHS = RHS is what we want to accomplish.

LHS = RHS implies that:

4n+4 = 8n+10

Subtracting 4n from both sides, we obtain:

4 = 4n+10

Subtracting 10 from both sides, we get:

-6 = 4n

Dividing both sides by 4, we find

-3/2 = n.

The statement P(-3/2) is invalid since n must be an integer greater than or equal to zero. As a result, our mathematical induction is complete. The mathematical induction proof is complete, demonstrating that P(n) is accurate for all n ≥ 0.

The tax intercept, the vertical asymptote of the graph of y, and the slope of the line tangent to the curve of y at the point t = 0 is t= a. We also found an expression for y' for ln(x¹) = 3* dx.

The given expression is y = ln(4 - at) - 1, where a is a positive constant.

The tax intercept is at t = a

We can find tax intercept by substituting t = a in the given expression.

y = ln(4 - at) - 1

y = ln(4 - aa) - 1

y = ln(4 - a²) - 1

Since a is a positive constant, the expression (4 - a²) will always be positive.

The vertical asymptote of the graph of y is at t = a. The vertical asymptote occurs when the denominator becomes 0. Here the denominator is (4 - at).

We know that if a function f(x) has a vertical asymptote at x = a, then f(x) can be written as

f(x) = g(x) / (x - a)

Here g(x) is a non-zero and finite function as in the given expression

y = ln(4 - at) - 1,

g(x) = ln(4 - at).

If it exists, we need to find the limit of the function g(x) as x approaches a.

Limit of g(x) = ln(4 - at) as x approaches

a,= ln(4 - a*a)= ln(4 - a²).

So the vertical asymptote of the graph of y is at t = a.

The slope m of the line tangent to the curve of y at the point t = 0 is m = a

To find the slope of the line tangent to the curve of y at the point t = 0, we need to find the first derivative of

y.y = ln(4 - at) - 1

dy/dt = -a/(4 - at)

For t = 0,

dy/dt = -a/4

The slope of the line tangent to the curve of y at the point t = 0 is -a/4

The given expression is ln(x^1) = 3x.

ln(x) = 3x

Now, differentiating both sides concerning x,

d/dx (ln(x)) = d/dx (3x)

(1/x) = 3

Simplifying, we get

y' = 3

We found the tax intercept, the vertical asymptote of the graph of y, and the slope of the line tangent to the curve of y at the point t = 0. We also found an expression for y' for ln(x¹) = 3* dx.

The expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:

d = (R / H) * h

To find an expression for the distance of the liquid surface from the top of the cone, let's consider the geometry of the inverted cone.

We can start by defining some variables:

R: the radius of the base of the cone

H: the height of the cone

h: the height of the liquid inside the cone (measured from the tip of the cone)

Now, we need to determine the relationship between the variables R, H, h, and d (the distance of the liquid surface from the top of the cone).

First, let's consider the similar triangles formed by the original cone and the liquid-filled cone. By comparing the corresponding sides, we have:

(R - d) / R = (H - h) / H

Now, let's solve for d:

(R - d) / R = (H - h) / H

Cross-multiplying:

R - d = (R / H) * (H - h)

Expanding:

R - d = (R / H) * H - (R / H) * h

R - d = R - (R / H) * h

R - R = - (R / H) * h + d

0 = - (R / H) * h + d

R / H * h = d

Finally, we can express d in terms of h:

d = (R / H) * h

Therefore, the expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:

d = (R / H) * h

The plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Sketching the graph of the piecewise function h(t) representing the relationship between height and time during the 20 seconds: The graph of the piecewise function h(t) is as shown below: We can obtain the local minima and maxima for the intervals of increase or decrease and other specific coordinates as below:

When 0 ≤ t < 5, there is a local maximum at (1.38, 655.78) and a local minimum at (3.68, 140.45).When 5 ≤ t ≤ 12, the function is decreasing

When 12 < t ≤ 20, there is a local maximum at (14.09, 4101.68)b. The acceleration when t = 2 seconds can be determined using the second derivative of h(t) with respect to t as follows:

h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435dh(t)/dt = -243t² + 824t + 241d²h(t)/dt² = -486t + 824

When t = 2, the acceleration of the plane is given by:d²h(t)/dt² = -486t + 824 = -486(2) + 824 = -148 ms⁻²e.

The plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Therefore, the plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Hence, the plane changes direction at the point where its velocity is equal to zero.

When 0 ≤ t < 5, the plane changes direction from going up to going down at the point where the velocity is equal to zero.

The velocity can be obtained by differentiating the height function as follows :h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435v(t) = dh(t)/dt = -243t² + 824t + 2410 = - 1/3 (824 ± √(824² - 4(-243)(241))) / 2(-243) = 2.84 sec (correct to two decimal places)

d. The lowest and highest altitudes of the airplane during the interval [0, 20] s. can be determined by finding the absolute minimum and maximum values of the piecewise function h(t) over the given interval. Therefore, we find the absolute minimum and maximum values of the function over each interval and then compare them to obtain the lowest and highest altitudes over the entire interval. For 0 ≤ t < 5, we have: Minimum occurs at t = 3.68 seconds Minimum value = h(3.68) = -400.55

Maximum occurs at t = 4.62 seconds Maximum value = h(4.62) = 669.09For 5 ≤ t ≤ 12, we have:

Minimum occurs at t = 5 seconds

Minimum value = h(5) = 241Maximum occurs at t = 12 seconds Maximum value = h(12) = 2129For 12 < t ≤ 20, we have:

Minimum occurs at t = 12 seconds

Minimum value = h(12) = 2129Maximum occurs at t = 17.12 seconds

Maximum value = h(17.12) = 4178.95Therefore, the lowest altitude of the airplane during the interval [0, 20] seconds is -400.55 m, and the highest altitude of the airplane during the interval [0, 20] seconds is 4178.95 m.e.

Therefore, the plane is speeding up while the velocity is decreasing during the interval 1.38 s < t < 1.69 s.f. The plane is slowing down while the velocity is increasing when the second derivative of h(t) with respect to t is negative and the velocity is positive.

Therefore, we need to find the intervals of time when the second derivative is negative and the velocity is positive.

Therefore, the plane is slowing down while the velocity is increasing during the interval 5.03 s < t < 5.44 seconds.g.

The maximum speed of the plane during the first 4 seconds: t e[0,4] can be determined by finding the maximum value of the absolute value of the velocity function v(t) = dh(t)/dt over the given interval.

Therefore, we need to find the absolute maximum value of the velocity function over the interval 0 ≤ t ≤ 4 seconds.

When 0 ≤ t < 5, we have: v(t) = dh(t)/dt = -243t² + 824t + 241

Maximum occurs at t = 1.38 seconds

Maximum value = v(1.38) = 1871.44 ms⁻¹Therefore, the maximum speed of the plane during the first 4 seconds is 1871.44 m/s.

(a) The cost function can be formed by adding the fixed costs to the variable costs per unit multiplied by the number of units produced. Let's denote the variable cost per unit as 'c' and the number of units produced as 'x'. The cost function would be: Cost(x) = 30,800 + c*x.

The revenue function can be formed by multiplying the selling price per unit by the number of units sold. Since the selling price is given as $1,572, the revenue function would be: Revenue(x) = 1,572*x.

To find the break-even points, we need to determine the values of 'x' for which the cost equals the revenue. In other words, we need to solve the equation: Cost(x) = Revenue(x).

(b) To find the vertex of the revenue function, we need to determine the maximum point on the revenue curve.

In a series circuit consisting of a capacitor, resistor, and inductor, with a 24-volt battery connected, we need to determine the charge on the capacitor at different time intervals. Given the values of the components (capacitor: 0.25 x 10 F, resistor: 5 x 10¹² Ω, inductor: 1 H) and the initial charge on the capacitor being zero, we can calculate the charge at specific time points and the limiting charge.

To calculate the charge on the capacitor at a given time, we can use the formula for charging a capacitor in an RL circuit. The equation is given by Q(t) = Q_max * (1 - e^(-t / tau)), where Q(t) is the charge at time t, Q_max is the maximum charge the capacitor can reach, tau is the time constant (tau = L / R), and e is the base of the natural logarithm.

Substituting the given values, we can calculate the time constant tau as 1 H / 5 x 10¹² Ω. We can then calculate the charge on the capacitor at specific time intervals, such as 0.001 seconds and 0.01 seconds, by plugging in the respective values of t into the formula.

Additionally, to determine the limiting charge, we need to consider that as time goes to infinity, the charge on the capacitor approaches its maximum value, Q_max. Therefore, the limiting charge is equal to Q_max.

To find the slope of a line tangent to the curve of the function y = f(x) = x² at a specific point P(x₁, y₁), we can use the equation m = (f(x₁ + h) - f(x₁)) / h, where h represents a small change in x.

In this case, we want to find the slope at point P(2, 4). Substituting the values into the equation, we have m = (f(2 + h) - f(2)) / h. Let's calculate the values needed to find the slope.

First, we need to find f(2 + h) and f(2). Since f(x) = x², we have f(2 + h) = (2 + h)² and f(2) = 2² = 4.

Expanding (2 + h)², we get f(2 + h) = (2 + h)(2 + h) = 4 + 4h + h².

Now we can substitute the values back into the slope equation: m = (4 + 4h + h² - 4) / h.

Simplifying the expression, we have m = (4h + h²) / h.

Canceling out the h term, we are left with m = 4 + h.

b) The values of x for which f(x) < -4 on the interval are x = (3/4)π + kπ, where k is an odd integer.

a) To solve f(x) = -4, we need to find the values of x that satisfy the equation.

Given:

f(x) = 4tanx

We want to find x such that f(x) = -4.

Setting up the equation:

4tanx = -4

Dividing both sides by 4:

tanx = -1

To find the solutions, we can use the inverse tangent function:

x = arctan(-1)

Using the unit circle, we know that the tangent function is negative in the second and fourth quadrants. Therefore, we have two solutions:

x = arctan(-1) + πk, where k is an integer.

Simplifying the expression:

x = (3/4)π + kπ, where k is an integer.

b) To determine the values of x for which f(x) < -4 on the given interval, we substitute the inequality into the function and solve for x.

Given:

f(x) = 4tanx

We want to find x such that f(x) < -4.

Setting up the inequality:

4tanx < -4

Dividing both sides by 4:

tanx < -1

Similar to part a, we know that the tangent function is negative in the second and fourth quadrants.

Therefore, the values of x for which f(x) < -4 on the interval are:

x = (3/4)π + kπ, where k is an odd integer.

We can answer the questions on functions in this way:

(a) Every function f defined on (-∞, ∞) that satisfies the condition that lim f(x) = lim f(x) = ∞ must have at least one critical point is false.

(b) The function f(x) = √x is differentiable at x = 0 is false.

(c) The function f(x) = |x| is not continuous at x = 0 is false.

(a) Every function f defined on (-∞, ∞) that satisfies the condition that lim f(x) = lim f(x) = ∞ must have at least one critical point.

A function can have a limit of infinity at every point without having a critical point.

For example, the function f(x) = x² does not have any critical points, but it approaches infinity as x goes to positive or negative infinity.

Thus, this statement is false.

(b) The function f(x) = √x is differentiable at x = 0.

The derivative of f(x) = √x is undefined at x = 0 because the slope of the tangent line is not defined for a square root function at x = 0.

So, the function f(x) = √x is not differentiable at x = 0, is a false statement.

(c) The function f(x) = |x| is not continuous at x = 0.

The absolute value function |x| has a well-defined value at x = 0, and the left and right limits of f(x) as x approaches 0 exist and are equal.

To find the volume of the solid generated by revolving the region bounded by the graphs of the equations y = x² + 424 and y = 152x³ about the x-axis  is approximately 2.247 x 10^7 cubic units.

First, let's find the points of intersection between the two curves by setting them equal to each other:

x² + 424 = 152x³

Simplifying the equation, we get:

152x³ - x² - 424 = 0

Unfortunately, solving this equation for x is not straightforward and requires numerical methods or approximations. Once we have the values of x for the points of intersection, let's denote them as x₁ and x₂, with x₁ < x₂.

Next, we can set up the integral to calculate the volume using cylindrical shells. The formula for the volume of a solid generated by revolving a region about the x-axis is:

V = ∫[x₁, x₂] 2πx(f(x) - g(x)) dx

where f(x) and g(x) are the equations of the curves that bound the region. In this case, f(x) = 152x³ and g(x) = x² + 424.

By substituting these values into the integral and evaluating it, we can find the volume of the solid generated by revolving the region bounded by the two curves about the x-axis is approximately 2.247 x 10^7 cubic units.

The integral ∫ f(x - 1) √(√x + 1)dx can be simplified to 2 (√b + √a) ∫ f(x)dx - 4 ∫ (x + 1) * f(x)dx.

To solve the integral ∫ f(x - 1) √(√x + 1)dx, we can use the substitution method. Let's consider u = √x + 1. Then, u² = x + 1 and x = u² - 1. Now, differentiate both sides with respect to x, and we get du/dx = 1/(2√x) = 1/(2u)dx = 2udu.

We can use these values to replace x and dx in the integral. Let's see how it's done:

∫ f(x - 1) √(√x + 1)dx

= ∫ f(u² - 2) u * 2udu

= 2 ∫ u * f(u² - 2) du

Now, we need to solve the integral ∫ u * f(u² - 2) du. We can use integration by parts. Let's consider u = u and dv = f(u² - 2)du. Then, du/dx = 2udx and v = ∫f(u² - 2)dx.

We can write the integral as:

∫ u * f(u² - 2) du

= uv - ∫ v * du/dx * dx

= u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du

Now, we can solve this integral by putting the limits and finding the values of u and v using substitution. Then, we can substitute the values to find the final answer.

The value of the integral is now in terms of u and f(u² - 2). To find the answer, we need to replace u with √x + 1 and substitute the value of x in the integral limits.

The final answer is given by:

∫ f(x - 1) √(√x + 1)dx

= 2 ∫ u * f(u² - 2) du

= 2 [u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du]

= 2 [(√x + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx], where u = √x + 1. The limits of the integral are from √a + 1 to √b + 1.

Now, we can substitute the values of limits to get the answer. The final answer is:

∫ f(x - 1) √(√x + 1)dx

= 2 [(√b + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx] - 2 [(√a + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx]

= 2 (√b + √a) ∫f(x)dx - 4 ∫ (x + 1) * f(x)dx

The probability of drawing a yellow rock and then the spinner stopping at a purple section is 3/56.

We are supposed to find out the probability of drawing a yellow rock and then the spinner stopping at a purple section.

The given information are as follows:

Number of blue rocks = 2Number of yellow rocks = 3Number of black rocks = 2Number of white sections = 9Number of blue sections = 3Number of black sections = 2Number of purple sections = 2.

Total number of rocks in the bag = 2 + 3 + 2 = 7

Total number of sections on the spinner = 9 + 3 + 2 + 2 = 16

Probability of drawing a yellow rock = Number of yellow rocks / Total number of rocks= 3/7

Probability of the spinner stopping at a purple section = Number of purple sections / Total number of sections= 2/16= 1/8.

To find the probability of drawing a yellow rock and then the spinner stopping at a purple section, we will multiply the probability of both events.

P(yellow rock and purple section) = P(yellow rock) × P(purple section)= (3/7) × (1/8)= 3/56

The last score of Carter will cause the display to be skewed to the right. Option D.

A distribution is considered skewed when the data is not evenly spread out around the average or median.

In this case, Carter's scores were 113, 117, 101, 97, 104, and 110. These scores are relatively close to each other, forming a distribution that is somewhat centered around a typical range.

However, when Carter played the game again and achieved a score of 198, this score is significantly higher than the previous scores. As a result, the overall distribution of scores will be affected.

Since the last score is much higher than the previous scores, it will cause the data to skew toward the right side of the distribution. The previous scores will be closer together on the left side of the distribution, and the high score of 198 will pull the distribution towards the right, causing it to skew in that direction.

To determine the limit, we can simplify the expression inside the limit notation and analyze the behavior as x approaches infinity.

The given expression is:

lim(x->∞) (24x³ + 4x² - 2x) / (28x + x + 5x + 5)

Simplifying the expression:

lim(x->∞) (24x³ + 4x² - 2x) / (34x + 5)

As x approaches infinity, the highest power term dominates the expression. In this case, the highest power term is 24x³ in the numerator and 34x in the denominator. Thus, we can neglect the lower order terms.

The simplified expression becomes:

lim(x->∞) (24x³) / (34x)

Now we can cancel out the common factor of x:

lim(x->∞) (24x²) / 34

Simplifying further:

lim(x->∞) (12x²) / 17

As x approaches infinity, the limit evaluates to infinity:

lim(x->∞) (12x²) / 17 = ∞

Therefore, the correct choice is:

B. The limit as x approaches infinity does not exist and is neither infinity nor negative infinity.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

To find the maximum and minimum values of the blood pressure function p(t), we need to examine the behavior of the sinusoidal term, -40sin(3t), within the given time interval. The function is a sine wave with an amplitude of 40 and a period of 2π/3. This means that the maximum value occurs at the peak of the sine wave (amplitude + offset), and the minimum value occurs at the trough (amplitude - offset).

The maximum blood pressure corresponds to the peak of the sine wave, which is 40 + 160 = 200 mmHg. To find the time at which this occurs, we set the argument of the sine function, 3t, equal to π/2 (since the peak of the sine wave is π/2 radians). Solving for t gives t = (π/2) / 3 = π/6 ≈ 0.524 seconds.

Similarly, the minimum blood pressure corresponds to the trough of the sine wave, which is -40 + 160 = 120 mmHg. Setting the argument of the sine function equal to 3π/2 (the trough of the sine wave), we find t = (3π/2) / 3 = π/2 ≈ 1.571 seconds.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

The integral using vertical cross-sections would be ∫∫R dx dy, and the integral using horizontal cross-sections would be ∫∫R dy dx.

When considering vertical cross-sections, we integrate with respect to x first, and then with respect to y. The region R is bounded by the curve y = ³√x, so the limits of integration for x would be from 0 to 8, and the limits of integration for y would be from 0 to the curve y = ³√x. Thus, the integral using vertical cross-sections would be ∫∫R dx dy.

On the other hand, when considering horizontal cross-sections, we integrate with respect to y first, and then with respect to x. The limits of integration for y would be from 0 to y = 0 (since y = 0 is the lower boundary). For each y-value, the corresponding x-values would be from x = y³ to x = 8 (the upper boundary). Therefore, the integral using horizontal cross-sections would be ∫∫R dy dx.

In both cases, the integrals represent the area over the region R bounded by the curve y = ³√x, with y = 0 and x = 8 as the boundaries. The choice between vertical and horizontal cross-sections depends on the context and the specific problem being addressed.

To find the volume generated by rotating the region bounded by the curves y = 3x and y = 0 about the line x = 4, we can use the method of cylindrical shells. The volume V is equal to the integral of the cylindrical shells formed by the region.

To calculate the volume using cylindrical shells, we need to integrate the area of each shell. The radius of each shell is the distance from the axis of rotation (x = 4) to the curve y = 3x, which is given by r = 4 - x. The height of each shell is the difference between the y-values of the curves y = 3x and y = 0, which is h = 3x.

We need to determine the limits of integration for x. From the given curves, we can see that the region is bounded by x = 2 (the point of intersection between the curves) and x = 0 (the y-axis).

The volume of each cylindrical shell can be calculated as dV = 2πrh*dx, where dx is an infinitesimally small width element along the x-axis. Therefore, the total volume V is given by the integral of dV from x = 0 to x = 2:

V = ∫[from 0 to 2] 2π(4 - x)(3x) dx

Evaluating this integral will give us the volume V generated by rotating the region about x = 4.
