Graphing Issue In my y=, the symbols to the left of it are all sideways triangles with bars next to it and it won't let me graph more than one function at a time. Please help!

Maybe the carrot or caret cursor can be cleared on a TI

When the calculator is in Alpha mode, the blinking square cursor symbol is replaced with the reversed-A symbol. This symbol indicates that the next key you press will insert the green letter above that key. To take the calculator out of Alpha mode, press [ALPHA].

You executed the Transform Application and it is still loaded in memory taking over the graphing duties from the native OS. You must unload it from memory.
Press the APPS key. Scroll and find Transfrm, then press ENTER. In the new screen select 1:Uninstall and press Enter.
Go to your Y= function editor to type in up to 10 functions.

you have an app turned on for graphing inequalities. Hit App, I am not sure what it is called, something to do with inequalities. Turn that off and your y= will be fine.

The Transfrm application has been executed previously. It remains in RAM and takes over the graphing duties of the native OS. You must Uninstall Transfrm (that does not mean delete it, just unload it from memory).
To do so,

1. press the [APPS] button.
   
2. Use arrow Up or Down (Up is faster) to reach Transfm.
   
3. Select it and press [ENTER].
4. In the new screen, select the number to the left of the Uninstall option.
5. Go to draw your graphs. You will be able to draw up to 10 graphs.
   

In the Y= editor, scroll down to the equation in question. Press left-arrow until the cursor goes over the symbol. Press ENTER repeatedly to cycle through the various graphing options.

Usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.

You can skip the next paragraph if you want

The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

Press the [Apps] key. Scroll down or up to reach the Transfm application. Select it and press [ENTER]. If that application was running you will see a new screen that tells you
Transfrm App

1. Uninstall
2. Continue
   

Press1:Uninstall.
Graphing functionalities will revert to the native OS

Another potential culprit is the Inequalz App. To uninstall it, do as for the Transfm and select the option that will unload it from memory.

To return your calculator's graphing equation to "Y=", press "MODE" from the home screen, then ensure that the option on the fourth row is set to "Func". Next, to show a hidden graph, access the Y= list, then press the left arrow key until the cursor is over the "=". Press "ENTER" to toggle visibility of that line.

Damn dude i had the same problem, after a while searching for something that can put this problem away i've finnaly found the way \o/! Try APPS->TRANSFRM-> UNNINSTALL! Hope u can make it!

cheers

The problem is causedby an application called "Inequalz".
To solve the problem, go to the Apps menu and select Inequalz,
then select "quit Inequalz".
This should solve the problem.

The symbol on the left of the Ysub1,2,etc. determines what type of graph it is. move the cursor to the left of Ysub1,2,etc. and hit enter
