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
N3(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 ).
• Be sure to input the X variable (
S)(X)) when generating a number
table. Any variable other than X is handled as a constant.
• If you are using a single function, input a function in the format f ( x ) only.
• Pol and Rec cannot be input in the function.
3. In response to the prompts that appear, input the values you want to use,
pressing
= after each one.
For this prompt: Input this:
Start?
Input the lower limit of X (Default = 1).
End? Input the upper limit of X (Default = 5).
Note: Make sure that the End value is always
greater than the Start value.
Step? Input the increment step (Default = 1).
Note: The Step specifies by how much the Start
value should be sequentially incremented as the
number table is generated. If you specify Start = 1
and Step = 1, X sequentially will be assigned the
values 1, 2, 3, 4, and so on to generate the number
table until the End value is reached.
• Inputting the Step value and pressing
= generates and displays the
number table in accordance with the parameters you specified.
• Pressing
A while the number table screen is displayed will return to
the function input screen in step 2.
