Precalculus: Inverses of Functions

by Texas Instruments

Overview

Students explore three ways to find the inverse of a function. First, students graph two scatter plots and find the line of reflection. Then, they will graph a line and use the x- and y-intercepts to create the graph of the inverse.

    In this activity, students find the inverse of a set of data points by graphing scatter plots. They will then find the line of reflection by finding the midpoint of the first data points and the midpoint of the last data points and connecting them.
