Editing A Functions; Using Data & Statistics Functions In Other Applications; Supported Function Types - Texas Instruments TI-NSPIRE Software Manual

Editing a functions

You can edit a function and update it on the work area.
1. You can edit a function in either of the following ways:
• Click on the curve to select it and drag to adjust the plotted
data.
• Double-click the equation and edit it as required to change the
plotted data
2. Press Enter after making all changes and the curve will update.
Using Data & Statistics functions in other applications
Data & Statistics functions are stored as variables, and may be used in
other applications, in the same manner as any other variable.
Note: Function numbers increment by next available. If you have defined
f1(x) and f2(x) in Graphs & Geometry, the first function you create in Data
& Statistics will be f3(x).

Supported function types

The following function types are supported in Data & Statistics
• Linear function; f(x)=b
