Drawing Multiple Graphs on the Same Screen
Use the following procedure to assign various values to a variable contained in an expression
and overwrite the resulting graphs on the screen.
1. From the Main Menu, enter the
GRAPH
mode.
2. On the Setup screen, change the “Dual Screen” setting to “Off”.
3. Make V-Window settings.
4. Specify the function type and input the function. The following is the syntax for function
input.
Expression containing one variable
( [ ) variable
(=)
value
value
...
value
( ] )
5. Draw the graph.
Example
To graph
y
= A
x
2
– 3 as the value of A changes in the sequence 3, 1, –1
Use the following V-Window settings.
Xmin = –5,
Xmax = 5,
Xscale = 1
Ymin = –10,
Ymax = 10,
Yscale = 2
