#### Activity Overview

In this activity, students will explore the different transformations of polynomial functions. First they will use spreadsheet to investigate the changes of the y values as a value is added to or multiplied by the function. Then, students will confirm their conjectures using a minimized slider on a graph page.

#### Key Steps

• In each problem, students are to change the value of the variable in the spreadsheet trying to determine how the graph changes. They will be looking for a change in y intercept, x-intercept, or shifts of the y-values to the left or to the right.

• Then, students will test their conjectures on Graphs pages by clicking the up and down arrows of the minimized slider. Investigations of three different polynomial functions enables students to generalize the effects of the transformation.

• Students will answer questions to apply their observations from the investigations of transformations.
