Chapter 3 specifically describes function graphing, but the
steps shown here are similar for each TI-83 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 Y= 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 [FORMAT] and select the graph format settings
(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-83 tools described in this chapter.
You can store the elements that define the current graph to
any of 10 graph database variables (GDB1 through GDB9,
and GDB0; Chapter 8). To recreate the current graph later,
simply recall the graph database to which you stored the
original graph.
These types of information are stored in a GDB.
• Y= functions
• Graph style settings
• Window settings
• Format settings
You can store a picture of the current graph display to any
of 10 graph picture variables (Pic1 through Pic9, and Pic0;
Chapter 8). Then you can superimpose one or more stored
pictures onto the current graph.
