CHAPTER 6
2. Drawing a Function Graph Using a List
<Example>
To draw the graph for “Y = {1, 2, 3} x
2
” in the rectangular coordinate system
using the list containing {1, 2, 3}, follow these steps.
1. First, input the equation.
opens the equation input screen.
2. Move the cursor to Y1. (If any equation is already
input, clear it.)

Three graphs are drawn as shown to the right.
{1, 2, 3} X

” are drawn.
The window settings in the graph shown to the right are
default values.
* After “L1 = {1, 2, 3}” is entered, “Y = L1X

There are ten options available in the OPE.
Assume that lists, L1 : {6, 4, 5} and L2 : {3, 9, 8} have
