you can reset all variables, without losing all your programs. you can hit 2nd>Mem(plus symbol)>reset>All ram Then verify that you wish to do so... It should reset to a working condition... If it doesn't then you may need to lose your programs in order to get your calc to a working condition.

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.

1.Press [MODE], scroll to set Function graphing mode.
2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists
3. Press [STAT][1:Edit] to enter data.
Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.
4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.
5.Press [2nd][STATPLOT]1 to select 1:Plot1
The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.
If you think that the curve look like a straight line you can try to do a linear regression.
Press [STAT] Arrow right to highlight [CALC]
Select [4: LinReg(ax+b)]
LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 press comma Press [VARS] Arrow right to select [Y:VARs][1:Function] [ENTER][1:Y1]
That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.
Hope it helps.

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.
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 some t
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.

Testimonial: "Thank you so much! It did the trick."
That means one (or more) of the variables you have in your function is not defined. Check to make sure you didn't misspell any variable name. Also, check to make sure you didn't run two variable names together. "ab" is the variable ab, not a times b.
