Best ResponseYou've already chosen the best response.1To find the inverse of any function. You start by replace the x and y variables. So in this case, You have the original function f(x)=4x8, f(x) is also y So y=4x8 Start by replacing x with y and y with x So x=4y8 Now solve the equation for y.

Best ResponseYou've already chosen the best response.1So x=4y8 Subtract the 4y from the right side and left side You have x4y=8 now subtract the x from both sides 4y=x8 Divide the whole equation by 4 So y=...........
