Notes 3-8
This document provides examples and explanations of inverse functions. It begins with examples of inverse operations like turning directions and mathematical operations. It then discusses the definition of an inverse function as one that undoes another function. Examples are given of finding the inverse of a squaring function and determining if functions are inverses using the Inverse Function Theorem, which requires checking if function compositions equal the identity. One example explains that two functions are not inverses because their composition does not equal the original input. Students are assigned homework problems practicing inverse functions.
