What Is a Table?
A table displays coordinate pair (
X
,
Y
) solutions for a defined
function. One column displays independent variable values
(
X
), and all others display corresponding dependent variable
values (
Y
).
On the TIN73, functions can be displayed in one of three ways,
as shown here with the function,
Y
1
=X

-4X+3
.
For more information about the Y= editor and function
graphing, see Chapter 9: Function Graphing.
The Y= editor (
&
) shows
an algebraic representation.
The Graph screen (

shows a graphic representation.
The Table screen (
