Did you put one in each of 2 y =???
Also, check your window to make sure the numbers fit the x and y values in both graphs

I want to know how to graph equations on the TI-84 calculator


You must cast the functions in the so-called functional form y=ax+b. Isolate y for both functions, then open the Y= function editor and type in the second member (right member) of y=ax+b.
You can enter both functions and have them graphed on the same screen. In that case one will be on the Y1= line, the other on the second line.
Make sure that both = signs in the Y= editor are highlighted if you want both functions on the same graph.

Cannot graph two equations together, & trig graphs are not correct.


At first in Y editor type Y1=2*cosx and for example y2=[5*exp(-x)]-5 and then graphing it. Set RAD mode of course. See captured images

My TI-84 PLUS calculator wont show the graph after i type in an equation. please help!


You need to fix your graph so that it shows the correct y-axis and x-axis.
It works best if you press the zoom button and then scroll to find the ZoomFit option.
Then the graph should show up.

My ti-84 is only graphing one linear equation in the y equal when i put two equations in it only show one


The following should help you draw several graphs.
When you enter a function you should press [ENTER] to validate. At the same time, the cursor moves to the next line. Verify that the = sign on the equation already entered is still highlighted.
If for some reason the = sign of an equation is no longer highlighted, use arrow keys to move cursor on the = sign and press [ENTER].

If only one = sign remains highlighted and all others are not, then in all probability the application Transfrm has been executed before and is still lingering in RAM. When in RAM, it takes over the graphing capabilities of the native OS. This prevents you from drawing more than one graph.You must unload it from memory.
  1. Press the [APPS] key.
  2. Scroll down to the line that shows Transfrm.
  3. Highlight it and press [ENTER].
  4. In following screen you are invited to Uninstall or continue.
  5. Press the number to the left of Uninstall. Validate if need be.
  6. Return to the Y= editor to type in functions to graph.

Graphing multiply equations


When you go to Y=, you should get a list that says:
Y1=
Y2=
Y3=
etc. You just enter the first equation into the Y1= space then hit ENTER and it will go to Y2=. Enter the second equation there. After you have entered all of your equations, push GRAPH and they should come up in order but they will all appear.

Also, make sure your window is set appropriately so that you are able to see all of the graphs.

Lastly, when you look at your Y= screen, are there funny looking arrows before the Y=? If so, do this:

  • Press [APPS] key
  • Select Transfrm from the menu
  • Press 1:Uninstall


  • Hope one of these are helpful!!
