Precalculus and Advanced Topics, Module 3, Topic C Overview

Students Having Fun

In Topic C students study inverse functions, being careful to understand when inverse functions do and do not exist, working to restrict the domain of a function to produce an invertible function.  They compare and create different representations of functions including tables and graphs.  Students compose functions to verify that one function is the inverse of another and work with tables of data to identify features of inverse functions. Special emphasis is given to the inverse relationship between exponential and logarithmic functions.
