To store the function
y
= 3

– 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

Variable 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

changes from –3 to 3, in
increments of 1

x
changes
during function calculation.
