Creating a Number Table from a

Function (TABLE)

TABLE generates a number table for x and f(x) using an input f(x) function.

Perform the following steps to generate a number table.

1.Enter the TABLE Mode.

On the fx-82/85/350ES PLUS, press , on the fx-95ES PLUS, press .

2.Input a function in the format f(x), using the X variable.

Be sure to input the X variable (#(X)) when generating a number table. Any variable other than X is handled as a constant.

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.
