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.
