An Introduction to Inverse Functions

I added a new file to my Documents to Download page this evening - a supplement to a section titled 1.5 Inverse Functions in Sheldon Axler's marvelous book Pre-Calculus: A Prelude to Calculus. This has always proven to be a difficult concept to teach within the bounds of a normal class period. I share this document with students as an extra resource that they can read through with the hopes that it will add clarity not confusion.
