Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
I put my equation into the y= screen and press the graph button at the top right corner and then it exits out of my y= equation screen and just has a 4 ? everytime i press the graph button after that it's like i'm actually hitting the 4 button ? help ?!
It seems that wires got crossed. I suggest you reset all RAM by the follwing steps
Ram cleared will be displayed on screen. [CLEAR] to go to the home screen.
If that does not solve your problem, reinstall the OS. Post a question on how to install OS, if you want, or read some of the posts on TI83/84/89 about same subject.
If nothing works, I am afraid you will have to repair the calculator.
Hope it helps.
