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.

Select two points P1 and P2 on the line. Read their coordinates P1(X_1,
Y_1), and P2(X_2, Y_2). If the points are given to you that is even better: you will not have to approximate their coordinates. The slope of the straight line that passes through P1 and P2 is the ratio s=(Y_2-Y_1)/(X_2-X_1). A slope is a number and cannot be graphed. The line that has the slope can be graphed if you have its complete equation y=slope*x + initial value. To graph a curve on the TI84 open the Y= editor, type in the second member (right side) of the function say on line Y1= then press the Graph function key.
After entering the first function to graph press the down arrow and when the cursor blinks after Y2 type in the second function you wish to graph. After you finished entering multiple functions make sure the graph setting under the window button are set correctly so every function will be visible at the interval you set. After that you hit Graph and you should see your graphs being plotted.
You have used the TRansfrm application. It remains in memory and takes over the graphing responsibilities from the native OS. You must kick it out of RAM (No, that will not delete it from the calculator).
Scroll along the list of APPS
Find TRansfrm and point to it.
Select the Uninstall option.
Open the [Y=] function editor and type in the functions (up to 10)
Use the [Y=] entry screen to enter the functions you want to graph. Make sure that the = sign after Y1, Y2 etc. is highlighted (black). If the = sign is not highlighted the corresponding function will not be drawn. You can can up to 10 functions, but what is the point of drawing so many if they overlap?
Anyway, to change the graph style of the curve for a particular function, use arrows to move to the line, then use left arrow to the bit of line that appears to the left of the Y. Highlight the segment an press ENTER. Each time you press ENTER the style changes to another one. Beware of the unconnected bubble style. During the drawing it will show the position of the point being drawn, but at the end, the whole curve, so to speak, evaporates.
As to simultaneous graphs, if it is important to you to have the graphs drawn for all the curves at the same time, you can enforce that by pressing [MODE], and using down arrow to reach the 6th line Sequential Simul. Use the right arrow to highlight Simul and press ENTER.
Whether drawn sequentially or simultaneously, all graphs will be displayed, except for the ones with the unconnected bubble as style.
I use one of the graphing APPS or do through a program. I have a users manual for TI 84 silver Edition that shows you how to archive\ unarchive to run programs here at this site. Usually, I tell people to just forget about the programs and use the simple concepts so, that they could operate their calculator better. But, if you notice in those program are actually more powerful than the programs you get on the web, because I wrote them to be flawless, or I only used programs that I knew would not clash and were very well written. Won't y1=(2/5)x-(11/5) and -3x+8 work?
Hi, you can try uninstalling the transformation app in your calculator. This does not really uninstall your application, it only prevents it from interfering with it. You should be able to graph multiple functions after that.
1) Go to APPS
2) Press Transfrm
3) Click Uninstall
