Exploring the Exponential Function (Electronic Format Only)

Activity Overview

In this activity, students study the exponential function. They differentiate between exponential growth and exponential decay from an equation. They identify the coefficient in an equation that represents the rate of growth/decay. Students also explain the effect of changes in the values of A and/or B - the coefficients of the equation.

Before the Activity

Set up the Transformation Graphing Application on the calculator using the TI Connect™ software

See the attached PDF file for detailed instructions for this activity

Print pages 42 - 50 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Select the Transformation Graphing application, enter an exponential function AB^x, and set the values of the coefficients to 1

Observe the graph

Keeping the value of B constant, change the value of A, and observe the effects on the y-intercept of the graph

Set A = 1 and increase the value of B

Observe that B controls the rate at which the function grows; the greater the value of B, steeper the curve and the function grows at a faster rate

Study various graphs, determine whether they represent growth or decay, and find the values of A and B

After the Activity

Students' will complete the Student Worksheet and answer questions listed on it.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
