Question about Texas Instruments TI-84 Plus Calculator

TI 84 will not graph multiple functions simultaneously

I have had the TI84 for more than a year. Recently, it stopped graphing completely because somehow the PLOT 1 PLOT 2 PLOT 3 at the top of the function (Y =) screen were highlighted. Now I can get one fuction at a time....anyone know how to make the TI84 graph multiple functions simultaneously?

Already tried highlighting multiple functions (and only one equal sign will highlight at a time) and already reset Mode to SIMUL. Have also tried changing the line type at the far left of the function...no effect.

    Evidently my transfrm apps has already been accidently activated. When I hit the apps and then transfrm, my calculator automatically launches a program over areas of polygons. The option to uninstall or continue isn't even an option. (This is the advice every site seems to offer me to uninstall the program. I need to uninstall it because it is causing difficulties in my graphing abilities.) HELP!
    Even the Texas instrument site offers nothing for my problem.

Turn off transformers. Go to apps and go all the way down until you reach transformers then hit enter. Then a menu should appear and hit uninstall that should fix it.

Trying to graph and error comes up as invalid dim 1:Quit


You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.
If this doesn't do it, could you post the function you're trying to graph?

Whenever I try to plot anything on the graph it says: ERR: INVALID DIM I need to graph problems such as x+1 over 2 or 1+5/x over 25/x squared.

In my Y= menu, any equation that I enter isn't graphed on my graph. At the top, by Plot 1 Plot 2 Plot 3, it says "X=" before them. Also when i do enter an equation, it says Error: invalid dimensions.


You must deactivate the Statistical plots.
Press [STAT].
In list that is displayed delect [4:PlotsOff] and press [ENTER]
Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.

When i grath, there is message " invalid dim"


I think you are saying that when you graph, you get the message "invalid dim"

If you are trying to graph from the y= screen it may me that you have one of the plots on. If this is the case, look at the top of the y= screen. If plot 1, plot 2 or plot 3 has darkened box around it, the plot is on and you need to turn it off. Move your cursor on top of the one that is highlighted and press enter. You should now have the plot turned off and should be able to graph from the y= screen.

Another way to do this is to press 2nd key, plus key and then 7, and then 1 and then 2. This will reset your ram.

Hope this helps

When trying to use the graph functions get error:Invalid dim


Look at the Y= screen. If If Plot 1, or more, is On (dark) along the top, you have to turn it off. Select STAT PLOT, (2nd Y=), then 4, (Plots Off), then Enter. Your screen should say Plots Off Done. Graph should now work.
