USING THE GRAPHING CALCULATOR (TI 83 PLUS) TO GRAPH AN
ABSOLUTE VALUE INEQUALITY
![Page 2: Example – Graph the solution set of Turn on your calculator and enter the Y= menu and enter the first part of the inequality Be sure to put the 2/5 in.](https://reader030.fdocuments.us/reader030/viewer/2022032723/56649cf75503460f949c743f/html5/thumbnails/2.jpg)
Example – Graph the solution set of
81555
2x
Turn on your calculator and enter the Y= menu and enter the first part of the inequality
Be sure to put the 2/5 in parenthesis.

To enter the absolute value sign, press the MATH button
Go to the right to the NUM tab
Press enter

Enter the rest of the left side of the inequality:
To enter the inequality symbol, press the 2nd key then press the MATH button
Choose option 6 and press enter

Finish entering the inequality
Press the ZOOM button then choose option 6

Here’s what we get:
Our graph is a conjunction between -1 and 7
1x 7x

Trouble shootingAre you getting the following error message?
This means that your calculator is trying to plot something that is not defined. This is a simple fix. Go back to the Y= menu

One or more of the plots are turned on. On my calculator, I have Plot1 turned on. To turn it off, scroll up to the Plot(s) that are on and press ENTER to turn them off.
Once all of the plots are turned off, it should graph like normal.

Are you getting this error message?
Easiest way to fix this is to press the ZOOM button the choose option 6 and it should graph normally
