Graphing Function Interaction
The Graphing Function Interaction is not one of the Portable Custom Interactions in the standard TAO package. It will need to be installed in a separate extension.
A Graphing Function interaction is useful if you would like the Test-taker to provide a visual answer in the form of a function type with two point coordinates.
If you wish to use the Graphing Function interaction, the corresponding extension will need to be installed first. See the chapter on the Extensions Manager for information on how to do this, or ask your systems administrator about the installation of this extension.
