All graph commands (except the Trace 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 y= x°-x 3 -24x2 + 4x+ 80 10x-30 Use the following range parameters.
