Answer:
To determine the inverse of function f, change f(x) to y, switch x and y, and solve for y.

Step-by-step explanation:
f(x) = ![\sqrt[3]{8x} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%2B4)
Change f(x) to y: y = ![\sqrt[3]{8x} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%2B4)
Switch x and y: x = ![\sqrt[3]{8y} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D%20%2B4)
Solving for y: x - 4 = ![\sqrt[3]{8y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D)
(x-4)^3 = 8y
y = 

Therefore: inverse of function f = 
We can’t solve this one because there is no 0, without 0 we can’t figure out what B is equal to
