**Finding the Inverse of a Function**

- First, replace f(x) with y . …
- Replace every x with a y and replace every y with an x .
- Solve the equation from Step 2 for y . …
- Replace y with f−1(x) f − 1 ( x ) . …
- Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
