Generating a Number Table and Using 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
