Generating a Number Table and U s ing It to Draw a Graph
After using a function to generate a number table, you can use the number table values to
draw a graph. You can use number table values to draw two different types of graphs: a
“connect type graph” on which points are connected by lines, or a “plot type graph” on which
points are simply plotted, without being connected.
Example: To generate number tables for the functions
y
= 3
x
2
– 2 and
y
=
x
2
as the value of
x
changes from –3 to 3 in increments of 1, and then use the generated values to
draw a graph
S\ Cla ss Pad Operation
(1) On the application menu, tap $ .
(2) On the Graph Editor window, input 3
x
2
– 2 in line
y
1, and
x
2
in line
y
2.
(3) Tap to display the View Window dialog box, and then configure it with the following
parameters.
xmin = –3, xmax = 3, xscale = 1
ymin = –2, ymax = 10, yscale = 2
(4) Tap to display the Table Input dialog box, and then configure it with the following
settings.
Start: –3, End: 3, Step: 1
(5) Tap .
• This generates the number table and displays the result on the Table window.
