Creating a Number Table from Two
Functions (TABLE)
TABLE generates a number table based on one or two functions. You can
use the function
f
(
x
) or the two functions
f
(
x
) and
g
(
x
). See “Configuring the
Calculator Setup” for more information.
Perform the following steps to generate a number table.
1. Press
N7(TABLE) to enter the TABLE Mode.
2. Use the X variable to input two functions, one in the format
f
(
x
) and the
other in the format
g
(
x
).
