Activity Overview
Students recognize the effects of changes in parameters on the graphs of linear, quadratic, and exponential functions.
Before the Activity
Install the Transformation Graphing application on the students' graphing calculators using one of these two methods:
TI-Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
TI-Navigator™ "send to class" feature
Load the Trans8 program on the calculator
See the attached PDF file for detailed instructions for this activity Print pages 101 - 107 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the Activity procedures:
Set up a scatter plot for the data set
Write the equation for the line model that matches the scatter plot
Repeat the steps for quadratic and exponential functions
Plot graphs for all three types of functions simultaneously and record the number of points ?hit?
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
