Chapter 3 specifically describes function graphing, but the steps
shown here are similar for each TI-82 STATS graphing mode.
Chapters 4, 5, and 6 describe aspects that are unique to
parametric graphing, polar graphing, and sequence graphing.
To define a graph in any graphing mode, follow these steps.
Some steps are not always necessary.
1. Press z and set the appropriate graph mode (page 3.4).
2. Press o and enter, edit, or select one or more functions in
the editor (page 3.5 and 3.7).

3. Deselect stat plots, if necessary (page 3.7).
4. Set the graph style for each function (page 3.9).
5. Press p and define the viewing window variables
(page 3.11).
6. Press y [

(page 3.13).
After you have defined a graph, press s to display it.
Explore the behavior of the function or functions using the
TI-82 STATS tools described in this chapter.
You can store the elements that define the current graph to any
of 10 graph database variables (
; Chapter 8). To recreate the current graph later, simply
GDB0
recall the graph database to which you stored the original graph.
These types of information are stored in a

You can store a picture of the current graph display to any of 10
graph picture variables (
8). Then you can superimpose one or more stored pictures onto
the current graph.
