k Storing a Function and Generating a Number Table
u To s t ore a function
Example To store the function y = 3x

– 2 in memory area Y1
Use f and c to move the highlighting in the Graph function list to the memory area
where you want to store the function. Next, input the function and press w to store it.
uVariable Specifications
There are two methods you can use to specify value for the variable x when generating a
numeric table.
• Table range method
With this method, you specify the conditions for the change in value of the variable.
• List
With this method, the data in the list you specify is substituted for the x-variable to
generate a number table.
u To generate a table using a table range
Example To generate a table as the value of variable x changes from –3 to 3, in
increments of 1
6(g)2(RANG)
-dwdwbw
The numeric table range defines the conditions under which the value of variable x changes
during function calculation.
Start ........... Variable x start value
End ............. Variable x end value
pitch ............ Variable x value change (interval)
After specifying the table range, press i to return to the Graph function list.
