Answer:
9x−12
Step-by-step explanation:
To find the inverse of a function, we find the function that reverses it. That means that for an input x and output y in a function, its inverse would have input y and output x.
For
![f^{-1}(x)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29)
(read "f inverse of x"), we must interchange the values of x and y.
![y=2x^2-8](https://tex.z-dn.net/?f=y%3D2x%5E2-8)
The inverse is
![x=2y^2-8](https://tex.z-dn.net/?f=x%3D2y%5E2-8)
, but we want to simplify it by solving for y.
