write an equation for the inverse?

Question

Write an equation for the inverse, given the function below.

 

f(x)=(x+1)^3

 

this is making me feel so dumb, im so lost

Answer 1

We switch places with x and f(x).  Let's say f(x) = y.

 

x = (y + 1)³

 

 

Now, we solve for y.

 

³√(x) = y + 1

 

 

-1 + ³√(x) = y
