How do you plot two functions? For example, how do we plot the functions

y=x² and y=x+4 ?

First, select the [Y=] key, just below the screen. You can enter up to 10 functions! Be sure the equal sign is selected! Only the functions with the equals highlighted will be plotted.

Be sure that the ranges are correct, and you have chosen the correct plot style. Select [ENTER] and the following graph will appear.
