**Using the Auto Table
Function**

A function must be entered into **
**in order to obtain its graph and its table. To view the graph and a table
of values for the function ,
enter the equation into .
To view the graph of the function, press **GRAPH**. The results are
shown below graphed in a** standard
window**. For more details on graphing functions click on **Graphing
a Function.**

The range of the values
must be set to view a table
of values for ,
just as a **Viewing
Rectangle** must be set for a graph. Press **2nd WINDOW [TBLSET] **to
set the starting value and the increment for X. In the graphic below, **TBLStart**
is set to 0 and **DTbl
**is set to 1. Both **Auto**'s
should be hightlighted. Press **2nd GRAPH [TABLE] **to view the table. Note
that the X values start at 0 and increment by 1. The down and up arrow keys
allow you to scroll throught the table.

To change the increment for X to one-tenth, press **2nd
WINDOW [TBLSET] **. Move the cursor with the **down arrow** key
to the 1 that appears next to **DTbl**.
Enter .1 in the place of the 1. Press **2nd
GRAPH [TABLE] **. The results are shown below. The X
values start at 0 and the increment is now one-tenth. Both the starting X value
and the increment can be changed to produce any table desired for the function.
The Y values for each X are computed by the calculator and displayed in the
table.

**Using the Ask Table Function**

Sometimes only one or a few specific table values are desired
for a function. For example, find the Y values associated with X= 3 and X =
10 for the function .
Since the function is already entered on the Y screen, press **2nd
WINDOW [TBLSET]**. Press the **DOWN ARROW** twice until the **Auto**
next to **Indpnt:** is highlighted. Press the **RIGHT ARROW **once to
highlight **Ask, **then press **ENTER**. Next press **2nd
GRAPH [TABLE]**. The table should appear empty as shown
in the third image below. Type **3** followed by **ENTER **to see what
value of Y is paired with 3. Type **10 **and then press** ENTER **to see
what Y is paired with 10. As shown below, f(3) = 13 and f(10) = 951.
