5. Press . On the Table Range dialog box that appears, input values for
Start (Default: 1), End (Default: 5), and Step (Default: 1).
6. Press  to generate the number table.
• Press  to return to the screen in
step 3.
Tip
• In the number table shown in step 6, you can change the value in the
currently highlighted x cell. Changing the x value causes the f(x) and g(x)
values in the same line to be updated accordingly.
• If there is value in the x cell above the currently highlighted x cell,
pressing  or  automatically inputs into the highlighted cell the
value equal to the value of the cell above it plus the step value. So also,
pressing  automatically inputs the value equal to the value of the cell
above less the step value. The f(x) and g(x) values in the same line are
also updated accordingly.
Note
• After pressing  in step 4 above, proceeding from step 5 onwards
without inputting anything for g(x) will generate a number table for f(x)
only.
• The maximum number of rows in the generated number table depends
on the setup menu table setting. Up to 45 rows are supported for the
"f(x)" setting, while 30 rows are supported for the "f(x),g(x)" setting.
• The number table generation operation causes the contents of variable x
to be changed.
Important: Functions input in this mode are deleted whenever the Input/
Output settings are changed in the Table Mode.
