Chapter 7
Using the Table
Above the three letter keys, , , and ,
you’ll see the following words in green: Y=, TBLSET, and TABLE.
These are the three things you needs to graph functions and each options represents a step in the
process of graphing functions. Since Y=, WINDOW, and GRAPH are in green, you will need to
press before being able to use any of the three.
There are three steps when graphing a function:
i. entering in the function(s) you want to view in a table,
ii. making sure your table setup is what you want, and
iii. using the table.
Each step is explained below.

This window serves the same purpose for both graphing and using tables. This is where you en-
ter in the function or functions you want to see in the table. y1, y2, ..., y99 represent the different
functions that you would want to use in a table.
