Overview of Steps in Graphing Functions

Graphing Functions
Tip: To turn off any stat
data plots (Chapter 16),
press ‡ 5 or use † to
deselect them.
Tip: This is optional. For
multiple functions, this helps
visually distinguish one from
another.
Tip: „ Zoom also changes
the viewing window.
Exploring the Graph
To graph one or more y(x) functions, use the general steps
shown below. For a detailed description of each step, refer to
the following pages. You may not need to do all the steps each
time you graph a function.
Set Graph mode (3)
to .
FUNCTION
Also set Angle mode,
if necessary.
Define functions on
Y= Editor (¥ #).
Select (†) which
defined functions to
graph.
Set the display style for
a function.
TI.89: 2 ˆ
TI.92 Plus: ˆ
Define the viewing
window (¥ $).
Change the graph
format, if necessary.

Graph the selected
functions (¥ %).
From the Graph screen, you can:
¦
Display the coordinates of any pixel by using the free-moving
cursor, or of a plotted point by tracing a function.
¦
Use the „
toolbar menu to zoom in or out on a portion of

Use the ‡
toolbar menu to find a zero, minimum,
