Press the Apps button and liik for the Inequalz application, and press [ENTER] to run it. If you do not find it, you must download it from education.ti.com >Downloads>Software and Apps >TI83/TI84 Plus Family.
Use the TI Connect software to transfer it to your calculator.
When you run Inequalz you should be aware that it will taker over the graphing capabilities from the native OS, and that you will have to unload it from memory if you want to recover the native graphing capabilities.

I want to graph an inequality but when i got to apps all it shows up is only finance
You don't need an app. Just press the Y= button and enter the inequality as if you're entering another function to be graphed. Then press left-arrow repeatedly to move to the diagonal line at the left end of the display. Press ENTER repeatedly to cycle through the different graph styles. If the inequality is of the form "y less than" or "y less than or equal to", select the shaded triangle below the line. If the inequality is of the form "y greater than" or "y greater than or equal to", select the shaded triangle above the line.

Changing Y= to Y greater than
Do you want to change from graphing functions to inequalities or the opposite? A complete sentence would help.
I am going to assume that you want to graph y=f(x) functions, but when you opened the Y= editor, you found unusual symbols.
If the is the case, then you must have run the Inequalz Application. It stays in memory and takes over the graphing from the native OS. Inequalz must be unloaded from memory to return control to the native OS.
Here is how to do it.

  1. Press the [APPS] key.
  2. In the list of Apps find Inequalz.
  3. Type the number in the list that corresponds to Inequalz and
  4. press ENTER
  5. The new screen displays INEQUAL RUNNING and 3 choices
  • 1:Continue
  • 2:Quit Inequal
  • About
Press 2:Quit Inequal to unloade the App from memory. Control will revert to the native OS, and you will be able to draw Y= graphs.
