In order to select additional graphs, you need to uninstall the Transformation Graphing App from their TI-84 Plus family calculators. Uninstalling the App does not erase it from the calculator; it disables it from interfering with the normal graphing modes. Below I have provided the steps to successfully uninstall the App.

- Press the [APPS] key
- Select the Transformation Graphing App (Transfrm)
- The calculator will prompt you to 1:Uninstall or 2:Continue
- Select 1:Uninstall
- Graph a function and the calculator should work fine
