Answer:

Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.

We can check that it is an inverse function by using a property of inverse functions:

If we plug in the f(x) function into the variable x of the inverse function, we should end up with x

It checks out!
22 = z + (-9) Switch the sides
z = 22 - (-9) Solve
z = 31 So, z = 31
Answer: y=3x-7
Explanation:
The y-intercept is -7 and the line is going up by a rate of 3.
