The TI

-86 plots four types of functions on the graph screen. To plot a graph, you must store

an unevaluated expression to a built-in equation variable.

Each activity in this section builds upon the activity that precedes it. You must start here
and perform the activities in the sequence in which they are presented. The first activity in
this section assumes you are continuing from the last activity in the previous section.

When storing to an equation
variable using 

, enter the

equation variable first, then
