Step-by-step explanation:
Feel free to ask if you don't understand what I'm doing here
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
(read "f inverse of x"), we must interchange the values of x and y.
The inverse is
, but we want to simplify it by solving for y.
