CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS
To enter in a function to graph, type the function in the command line.
Example:
You want to graph
y
= 2
x
+ 1
. Enter that in for
y
1
by using the arrows to move the cursor next
to
y
1
. Then type
in to the command line. When you press
, that
information will be saved for
y
1
.
Example:
You also want to graph
y
=
x
2
−
2
x
−
8
. Enter that in for
y
2
by using the arrows to move the cursor
next to
y
2
. Then type
in to the command line. That
information is now saved for
y
2
.
If you look at both
y
1
and
y
2
, you will see a check mark next to each. This indicates that
y
1
and
y
2
will both be graphed. It is possible to have functions saved but not graphed. The way to
do this is to uncheck the function. Look at the
menu at the top of the screen. This option will
check or uncheck an function. You must first highlight a function by scrolling up or down, and
then press
.
The
F6 Style
menu will change the style of line graphed. You can experiment with this later.
Make sure both functions you entered have checks and continue to the next step.
