Before graphing y(x) functions, you must select FUNCTION graphing. You may also
need to set the Angle mode, which affects how the TI-89 Titanium graphs trigonometric
functions.

2. Set the Graph mode to FUNCTION. Refer to “Setting Modes” in Operating the
Calculator.
For graphs that do not use complex numbers, set Complex Format= REAL.
Otherwise, it may affect graphs that use powers, such as x1/3.
While this module specifically describes y(x) function graphs, the calculator lets you
select from six Graph mode settings.
1. Press 3 to display the MODE dialog
box, which shows the current mode
