Using the graphing function in Programs
If you use the graphing function within a program, it makes it
possible that complex and long formulas can be represented
in graph form. Also graphs can become overwritten continu-
ally. All the graphing commands (except the trace function)
can be included within the program.
The value ranges can be written within the program.
Generally, the graphic operations can be used within the
program without the need of modifi cation.
Example:
Graphically determine the number of solutions that will sat-
isfy the following two equations:
4
3
Y=x
-x
-24x
Y=10x-30
Use the following parameters:
Xmin:
Xmax:
Xscl:
First, program the value ranges. Make sure that the values
are separated by commas.

+4x+80
-10

Ymin:
Ymax:
Yscl:
-120
