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

A function entry field displays in the work area.

Note: You can edit the function's expression typed in the entry field.

However, the function graphed in Data & Statistics cannot be

manipulated or moved around the work area. To do that, use Graphs

3. Type the function in the entry field, and press

Note: You can rename the function by typing over f1(x): with another

name, if you choose.

The function graphs in the work area and is saved as a variable for

use in other applications.

Using Data & Statistics

menu, select Plot Function.
