The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:
In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!

Once you enter an equation the corresponding equal sign is highlighted by default. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted. If one is not highlighted, move the cursor on it and press ENTER.
If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER]
Command PlotsOff echoes on main screen. Press [ENTER], screen displays Done.
If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You shouild make it a habit to clear the RAM every time you start a new type of problem.
Hope it helps.

Testimonial: "Clearing the RAM really helped thanks! Now I can show my students what to do. "
A) Before drawing function Y1=f(X), R1=F(Theta), (X1=f(T0, Y1=f(T))
you should turn the statistical plots OFF.
To turn statistical plots off
B) If you cannot draw more than one function
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.
Graphing functionalities will revert to the native OS
Another potential culprit is the Inequalz App. You recognoze that Inequalz is runnibg if the [ Y=] editor screen shows tabs at the bottom
To uninstall it, do as for the Transfm and select the option that will unload it from memory.
