Editing A Function; Changing The Settings For A Function Table - Texas Instruments TI-NSPIRE Software Manual

As you move through the table, Lists & Spreadsheet generates the
function values based on the independent variable (shown in the
leftmost column). Scrolling upward from 0 displays negative values
of the independent variable.

Editing a function

Besides using the other applications, such as Calculator and Graphs &
Geometry, you can edit a function definition in the function table.
Changes that you make are reflected in the other applications
automatically.
1. Double-click the function's expression.
2. A cursor appears in the expression.
3. Edit the expression, and then press
4. The table for the function is updated, and the Graphs & Geometry
graph of the function is also updated.

Changing the settings for a function table

Each function table uses initial settings that make it easy to scroll
through values. If you prefer, you can set the Table Start and Table Step
values manually, and you can choose to enter values manually for the
independent and/or dependent variable.
