This page supports the Introducing Dynagraphs activity from the Dynagraph unit. You will investigate dynagraphs of several different functions. To get a feel for the behavior of each function, you will drag the independent variable and observe the resulting motion of the dependent variable.

The term dynagraph was coined by Paul Goldenberg, Philip Lewis, and James O’Keefe in their study “Dynamic Representation and the Development of a Process Understanding of Functions” published by Education Development Center, Inc., and supported in part by a grant from the National Science Foundation.
In the activity Create a Dynagraph, you can construct your own dynagraph for linear functions, using only geometric transformations (dilation and translation) to accomplish the construction.
