TIp 3:
Graphing a Function in the Standard Window
for step-by-step instructions for defining functions. Your Y= editor should look like this.

Define a Different Viewing Window for Your Graph
View the table of (
X,Y
) values created by
Y
1
=
50X
to help you redefine window values. Start the
table at
L
3 and increment the values by 1. See
³
TIp 4:
Creating a Table
for step-by-step
instructions for creating a table.
Tip:
You can choose any
X
values for the table. For this exercise, you view a table of values when
L
3
X
3. When you set the table to
start at
L
3 with increments of 1, you can see the relationship between
X
and
Y
near the origin of the graph.
Your table should look like this:
