Exponential Reflections

Activity Overview

Students determine that the inverse of the exponential function is the natural log function by plotting the inverse of exponential solution points.

Key Steps

Step 1

Students will plot the inverse of points from an exponential function to discover it is the natural log function.

Step 2

Students will also explore the inverse of the function y = 10x.
