You can graph functions that can be expressed in the format
y
=
f
(
x
).
Example
To graph
y
= 2
x

Use the following View Window parameters.
Xmin = –5
Ymin = –10
Xmax = 5
Ymax = 10
Xscale = 2
Yscale =

1. In the set up screen, specify “
Y=” for Func Type and then press J.
2. Input the rectangular coordinate (Y =) expression.
