Graphing Functions
You can graph functions by typing them in Data&Statistics, or you can graph functions
defined in other applications.
Graphing Functions Using the Plot Function Tool
You can use the Plot Function tool to plot functions in a work area that already includes
a plot on the axes. Plot Function lets you specify and graph a function for comparison
to an existing plot.
To use the Plot Function tool:
1. Create or open a problem that includes variables (from Lists&Spreadsheet) that
are plotted on a Data&Statistics work area. Ensure that your work area contains
both a horizontal axis and a vertical axis scale.
2. From the Analyze menu, click Plot Function.
A function entry field displays in the work area.
