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.
7.1 Entering in Equations
Press to enter the Y= screen
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.
