The x->2- says you’re coming towards 2 from numbers less than 2.
The x->2+ says you’re coming towards 2 from numbers greater than 2.
See the attached photo.
The other one is #5.
Since there is an open circle at (0,0), this says there really isn’t a point there. f(0) is undefined. (You might need to say DNE for the computer.)

solve for y:
x^3 + (1/a)y= xy+9
Answers
Step-by-step explanation:
[tex] {x}^{3} + ( \frac{1}{a} )y = xy + 9[/tex]
[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
Divide both sides by x-1/a
[tex] \frac{x {}^{3} - 9}{x - \frac{1}{a} } = y[/tex]

The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
Answers
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.
Find the value of x and
y if x-y=3 and 2x+3y=4
Answers
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5
2x+3y=4
Using elimination we can multiply the top equation by -2 to Eliminate the x values. Doing this gives us
-2(x-y)= -2(3)
Simplifying we have
-2x+2y=-6
And then adding the second equation, we can have a system of two equations where the x eliminates
-2x+2y=-6
+2x+3y=+4
Adding we get that
5y=-2
Dividing by 5 on both sides gives us y=-2/5
We can substitute this y term in for the first equation. Doing so we have
x-(-2/5)=3
using the a-(-b)=a+b rule we get
x+2/5=3
Thus x=3- 2/5
So using a calculator we can say that x=13/5.
Thus your answers are x=13/5 and y=-2/5

What is a rational function?
In mathematics, a rational function is any function that can be described by using a rational fraction, which is an algebraic fraction such that each the numerator and the denominator are polynomials. The coefficients of the polynomials need no longer be rational numbers; they'll be taken in any field k.
A rational function is one that can be written as a polynomial divided by a polynomial. for the reason that polynomials are defined everywhere, the domain of a rational feature is the set of all numbers except the zeros of the denominator. example 1. f(x) = x / (x - 3). The denominator has only one 0, x = 3.
