Characteristics of Exponential Functions

Updated on 06/12/2015

Activity Overview

Investigate how the graph of an exponential function changes when 0 < b < 1, b = 1, or b > 1.

Objectives

  • Students will identify the characteristics of exponential functions of the form f(x) = bx, where b > 1
  • Students will identify the characteristics of exponential functions of the form f(x) = bx, where 0 < b < 1

Vocabulary

  • Exponential function

About the Lesson

This lesson involves investigating how the graph of an exponential function changes when 0 < b <1, b = 1, or b >1. As a result, students will:

  • Graph an exponential function.
  • Describe the domain, range, and y-intercept of the exponential function.
