Defining a Graph
This chapter describes the process for graphing functions in
Func
graphing mode, but the
process is similar for each TI
-86 graphing mode. Chapters 8, 9, and 10 describe the unique
aspects of polar, parametric, and differential equation graphing modes. Chapter 6 describes
various graphing tools, many of which you can use in all graphing modes.

� Set the graphing mode (page 74).
� Define, edit, or select one or more functions in the equation editor (pages 76 and 77).
� Select the graph style for each function (page 79).
� Deselect stat plots, if necessary (page 81).
� Set the viewing window variables (page 81).
� Select the graph format settings (page 83).
� Define, edit, or select one or more functions in the equation editor (pages 76 and 77).
