Solution 10383: Shading Above or Below a Function on the TI-82

How can I shade above or below a function on the TI-82?

Using the shade command, the TI-82 can shade a specific area of the graphing window. This function is accessed by pressing [2nd] [DRAW] [7].

The first two arguments in the shade command define the area that will be shaded. The first is the lower bound; the second is the upper bound. So for example when working in the standard viewing window, to shade the area above x², the following command would be entered on the home screen of the TI-82.

In this example x² is the lower bound, and 10, the top of the viewing window, is the upper bound.

Please see the TI-82 guidebook for additional information.
