Here are two problems on finding inverse functions.

Follow these steps:

1. Rewrite the function as *y* = [instead of *f*(*x*) = ].

2. Switch *x* and *y*.

3. Solve for *y*.

4. Rewrite the new function as *f *^{-1}(*x*) =.

On both of these problems, I did some extra rearranging at the end to make the final function look nicer. I apologize for the clutter.
