a. The functions f(x) = (x - 2) and g(x) = (x + 3) do not intersect or have any zeros. b. The graphs of f(x) = (x - 2) and g(x) = (x + 3) are parallel lines. c. There are no intervals where f(x) > g(x), but g(x) > f(x) for all intervals. d. The domain and range of both functions, f(x) and g(x), are all real numbers.
a. To find the point of intersection or zeros, we set f(x) equal to g(x) and solve for x:
f(x) = g(x)
(x - 2) = (x + 3)
Simplifying the equation, we get:
x - 2 = x + 3
-2 = 3
This equation has no solution. Therefore, the two functions do not intersect.
b. We can sketch the graphs of the two functions on the same set of axes to visualize their behavior. The function f(x) = (x - 2) is a linear function with a slope of 1 and y-intercept of -2. The function g(x) = x + 3 is also a linear function with a slope of 1 and y-intercept of 3. Since the two functions do not intersect, their graphs will be parallel lines.
c. To find the intervals for when f(x) > g(x) and g(x) > f(x), we can compare the expressions of f(x) and g(x):
f(x) = (x - 2)
g(x) = (x + 3)
To determine when f(x) > g(x), we can set up the inequality:
(x - 2) > (x + 3)
Simplifying the inequality, we get:
x - 2 > x + 3
-2 > 3
This inequality is not true for any value of x. Therefore, there is no interval where f(x) is greater than g(x).
Similarly, to find when g(x) > f(x), we set up the inequality:
(x + 3) > (x - 2)
Simplifying the inequality, we get:
x + 3 > x - 2
3 > -2
This inequality is true for all values of x. Therefore, g(x) is greater than f(x) for all intervals.
d. The domain of both functions, f(x) and g(x), is the set of all real numbers since there are no restrictions on x in the given functions. The range of f(x) is also all real numbers since the function is a straight line that extends infinitely in both directions. Similarly, the range of g(x) is all real numbers because it is also a straight line with infinite extension.

In the diagram below, how many different paths from A to B are possible if you can only move forward and down? A 4 B 3. A band consisting of 3 musicians must include at least 2 guitar players. If 7 pianists and 5 guitar players are trying out for the band, then the maximum number of ways that the band can be selected is 50₂ +503 C₂ 7C1+5C3 C₂ 7C15C17C2+7C3 D5C₂+50₁ +5Co
There are 35 different paths from A to B in the diagram. This can be calculated using the multinomial rule, which states that the number of possible arrangements of n objects, where there are r1 objects of type A, r2 objects of type B, and so on, is given by:
n! / r1! * r2! * ...
In this case, we have n = 7 objects (the 4 horizontal moves and the 3 vertical moves), r1 = 4 objects of type A (the horizontal moves), and r2 = 3 objects of type B (the vertical moves). So, the number of paths is:
7! / 4! * 3! = 35
The multinomial rule can be used to calculate the number of possible arrangements of any number of objects. In this case, we have 7 objects, which we can arrange in 7! ways. However, some of these arrangements are the same, since we can move the objects around without changing the path. For example, the path AABB is the same as the path BABA. So, we need to divide 7! by the number of ways that we can arrange the objects without changing the path.
The number of ways that we can arrange 4 objects of type A and 3 objects of type B is 7! / 4! * 3!. This gives us 35 possible paths from A to B.

Someone help please!
The graph A is the graph of the function [tex]f(x) = -x^4 + 9[/tex].
What is the end behavior of a function?The end behavior of a function refers to how the function behaves as the input variable approaches positive or negative infinity.
The function in this problem is given as follows:
[tex]f(x) = -x^4 + 9[/tex]
It has a negative leading coefficient with an even root, meaning that the function will approach negative infinity both to the left and to the right of the graph.
Hence the graph A is the graph of the function [tex]f(x) = -x^4 + 9[/tex].
