TI 89 Calculus > Table of Function Values on the TI89

Creating a table of function values by hand can be a time consuming process, especially for more complicated functions. A table of function values on the TI89 gives you a visual clue about how a set of data might be behaving. The **TI-89 graphing calculator** can create a **table of values** for any function in seconds.

## How to Create a Table of Function Values on the TI-89

The following example works for *any *function, not just the one listed.

Example problem: Create a table of function values on the TI-89 for the following function:

**f(x) = x ^{2} + 3x**

Step 1: Press the HOME key.

Step 2: Press the diamond key (♦) and F1 together to get into the y = editor.

Step 3: Press the ENTER key to move the cursor to the input line at the bottom of the y editor.

Step 4 Press x ^ 2 + 3 x, and then press ENTER to enter function into the “y1 =” slot.

Step 5: Look to the left of the Y1 slot to make sure there is a check mark next to the function. If there isn’t a check mark, press the F4 key to add a check mark.

Step 6: Press the diamond key and F4 together to open up Table Setup screen.

Input the starting x-value in the first slot and then specify the increment between values in the second slot. For example, type 1 into the “tblstart” box, then press the down arrow and then type 5 for the increments.

Step 7: Press the diamond key and F5 together to view the table.

**Tips:** If you need to enter the Table Setup screen again to change values, press F2 when you are viewing the table.

The table of values you generate will contain values for each checked function, so make sure you only have a check mark next to the function you want to draw a table for.
