Determine the inverse function

Replace f(x) with y

Swap the positions of x and y

Multiply both sides by -2


Square both sides


Make y the subject

The inverse has been solved. So, we need to replace y with f'(x)

Next, is to determine the interval

Change inequality to 

Hence, the inverse function is:
