Thanks flutedude! That was driving me nuts.
It was the Transfrm app (at least it was for mine). Select it from your APPS list and then Uninstall.

Some time or other she played with the Transfrm Application. It remains in memory and takes over the graphing capabilities of the native OS. It must be kicked out of memory.

  1. Press [APPS]
  2. Use Up or Down arrows (Up is faster) to get to the bottom of the APPS list.
  3. Locate [:Transfrm], highlight it and press [ENTER]
  4. In subsequent screen, select the [UNINSTALL] option.
  5. Go back to the [Y=] screen and enter or edit your functions.
  6. Press [GRAPH] when finished entering the functions.

I am not aware that the Casio FX-9750GPlus has a LIMIT application. If it does I would like to know how to find it.
As to graphing, read what follows. Window questions is at the end.

I will show you how to draw a simple function such as y=5*X 2. The method is the same reagrdless of the complexity of the function.

  1. Turn calculator ON. If you do not see several icons press [MENU].
  2. Use arrow to select the [GRAPH] application and press [EXE].
  3. In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
  4. Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
  5. At the position of the cursor type 5 then press the [X, theta,T] key, under the [ALPHA]. On the screen appears 5X, complete your equation by typing [ ] 2
  6. Press [EXE] to store function.
  7. If you want to draw other functions, it is time to do so on that screen.
  8. When done, press [F6:Draw].
  9. If the screen does not show a lot of the function, you can use the arrow keys to pan (move the center of the graph. You can pan Up, Down, Left, or Right.

How do u store linreg(ax+b)as y1 on ur graphic calculater


When you press [STAT] and right Arrow to highlight CALC you see two linear regression model [4:LinReg(ax+b)] and [8:LinReg(a +bx)]
If you select [4: ...] the command echoes on main calculator screen as LinReg(ax+b) and a blinking cursor
If you press [ENTER] you will get your equation, a, b, and r^2 if DiagnosticsOn command has been executed before. However you will not be able to see the line of best fit on top of the raw data scatter plot.

To save the equation of best fit in a function variable, ex Y1, you complete the command as follows
LinReg(ax+b) [VARS][=>][Y-VARS][1:Function][1:Y1]
The Y1 variable will appear on main calculator screen, and you have
LinReg(ax+b) Y1
Press [ENTER]
Screen display the equation, its parameter and its correlation coefficients (if so configured).
Press [GRAPH] to draw the line of best fit on top of the scatter plot.

Here are two screen captures to show you the equation and the line of best fit.

As you can see from the value of r^2, and the graph, a linear regression does not seem good.

I can't graph more than one equation in the y= area of my Ti 84+


Hello,
The marking that so puzzle you define the type of line (or dots) to represent the graphs. Enter as many functions as there are Y variables.
After entering a function press [ENTER] to jump to the next one.
When finished entering all functions press GRAPH. If you want graphs drawn one after the other, in MODE highlight Sequential (6th line) and press ENTER. If you want graphs drawn simultaneously, in MODE (6th line) highlight Simul and press ENTER. Press 2ND QUIT to return to previous screen . Execute graph again.
Hope itr helps.

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!!
