12-13 Using the Graph Function in Programs —
By using the graph function in programs, you can graphically represent long, complex
equations and overdraw graphs a number of times. All graph commands (except the Trace
Function) can be used in programs. You can also specify range parameters in programs.
*All of the explanations provided here are performed using the Program Mode only. Note,
however, that you can also perform the same operations in the File Editor Mode.
Example| To graphically represent the number of solutions (real roots) that satisfy
both of the following equations
yoxt—x3— 24x? + Ax+80
y=10x-30
Xmin : —10
Use the following range parameters.
Range, (—), 1,8, +, 1,8, °,2,+,(-),1,2,0,+51,5,0,+5,0
Finally, program the equation for the second graph.
