Question about Texas Instruments TI-84 Plus Calculator

1 Answer

Plotting two graphs

Hello! I bet this question is stupid, but can you please reply ASAP. I want to plot more than one graph on my calculator but I can't! After pressing the Y= button, the left side of the Y1 and Y2 seems to show a forward sign instead of a diagonal sign that enables me to plot more graphs. I know this because my teacher's calcu lator has a different sign. (e.g. Theirs show /Y1=). How can I change my settings? Or do I have to install something. Please help! Thanks

    Oh! No need for an answer, already found it on the internet... Haha, just in case anyone needs help with the same thing. Hit APPS > Transform > uninstall

    Yes that is the answer. But the problem with transformers is that they test the plot points when it comes to graphing differently even after installation. You may want to archive everything and clear the ram to reset this. It will not reset because you hit uninstall. Some examples of this flaw is when you try to graph equations like (5x+5)/(3x-2) or something to that effect. The transformers really screwed me up on a test about those.

Go into the Y= editor by pressing the Y= key. Select a function, then press the left-arrow a couple of times. Now press ENTER and see whether the symbol on the far left changes. If so, you've just changed the function style. Press ENTER repeatedly to select the function style. Your choices are Line, Thick, Above, Below, Path, Animate, and Dot.
