We have the function

1. For f^-1:
Let y = f(x) = (x+6)^3
Switch x and y to get:

And solve for y

And we have y = f^-1(x)

3. For f^-1 o f:

Solve
![\begin{gathered} =f^{-1}((x+6)^3) \\ =\sqrt[3]{(x+6)^3}-6 \\ =x+6-6 \\ =x \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3Df%5E%7B-1%7D%28%28x%2B6%29%5E3%29%20%5C%5C%20%3D%5Csqrt%5B3%5D%7B%28x%2B6%29%5E3%7D-6%20%5C%5C%20%3Dx%2B6-6%20%5C%5C%20%3Dx%20%5Cend%7Bgathered%7D)

Answer:
x = 4, y = 2
Step-by-step explanation:
3x - 2y = 8
-2y = -3x + 8
y = 3/2x - 4
2x + 4(3/2x - 4) = 16
2x + 6x - 16 = 16
8x = 32
x = 4
3(4) - 2y = 8
12 - 2y = 8
-2y = -4
y = 2
