Hello,
Reset the memory to defaults and you will not get the error.
[2nd][MEM][7:Reset][Defaults] [2:Reset] [ENTER]. Press [CLEAR] and them [Y=] to enter the function. No need to set Zoom. Defaults work fine for y1= 4X+3.
Press [GRAPH].
Hope it helps

Hi Fred,
Go to this site and download my Ti 84 plus (it might be the silver edition), manual on how to unarchive/archive to run program. It will show you how to delete x in the memory of your calculator. Plus, you can use it for future reference. I think x in the memory has been used so if you delete it, it should work. Nice trick using Zoom instead of entering the window every time.

    When I said this site, I mean FixYa! And check your graph window settings just to make sure everything looks right, and all plots are off.

    You got the error because, you went over specified limits by hitting the Zstandard key.

    If you Zoom Fit would solve your problem.

When graphing, after a formula is entered and the graph button is pushed, all I get is "ERR: WINDOW RANGE" What needs to be done? cewatts@live.com


Start by pressing ZOOM (the center function key on the very top row of the keyboard, just below the display) and select 6:ZStandard. This will set the window range to the standard default. After that, you can either zoom in on an area of interest or press WINDOW (just to the left of the ZOOM key) and enter in the window range.

How to set up mode for graphing


To draw a graph, it helps if you know approximately where it is going to show up so that you can set up a window.
Try this:
Press the [Y=] button
Enter the following equation: 5*x^2-5*x (five x-squared minus five times x) by pressing the following calculator keys:
5 X (times) x^2 (x squared key) - (minus) 5 X (times) x (key labled x,t,n) in between the ALPHA and STAT keys
now press the zoom key and select #6 - ZStandard (this will give you a standard zoom)
You should see a parabola drawn on the screen.
If you enter in some equation and do not see it on the screen, you can try zooming out (zoom key) or setting up your display window, using the window key.
This is where it helps to know where your x and / or y intercepts are.
From there, you can use trace to move around the graph, 2nd+graph (table) to see your x and y intercepts.

Hi , I haVE TI84 SILVER EDITION AND i LOST THE MANUAL ON HOW TO OPERATE IT iM TRYING TO DO GRAPH AND i CAN'T CAN YOU HELP ME I


Here is the link to the manual.
Here is a short tutorial to get you started.
First thing to do before any new type of graphing problem
1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

Second thing: Clear the statistical lists
2. Press [2nd][0][PGRM] DownArrow to point to ClrAllLists.
3.Press [ENTER][ENTER]

Third thing : Configure the graph type to be FUNCTION graph
4. Press [MODE]. If FUNC (on fourth line) is highlighted. Press [Y=] and start entering the functions.
5. If FUNC is not highlighted, use Down arrow till 4th line, highlight FUNC and press [ENTER]. Press Press [Y=] and start entering the functions.

Fourth thing: Enter function and select them for graphing
1. As you start entering the function Y1=, notice that the = sign becomes highlighted. Press [ENTER] when Y1 is typed in. Make sure the = sign for Y1 remains highlighted as cursor moves to Y2=.
2. Keep entering the functions and verifying that their = signs remain highlighted as cursor moves to another equation.
3. When finished press [ENTER]
4. Look at the graph style for each function: it is a bit of line to the left of each Y. Here is a picture of all the 7 styles.

5d53e23.jpg

To set a graph style, highlight the style to the left of the Y, and press [ENTER]. Each time you press [ENTER] you see a new style, in the order shown on picture.
Avoid the style of Y6, it is bubble, and as such will burst and disappear once graph is finished. Avoid also the triangular ones (for Y3 and Y4) they will shade areas of the graph, and may hide other functions.

Fifth thing: Graph Functions.
1. You can press [GRAPH] to see your graphs.
2. If one curve is missing (and you have not set its style to be rhe bubble), it may be due to the Window dimensions.

Sixth Thing: Set Window dimensions and Zoom.
1. Press [ZOOM][6:ZStandard] to use standard window dimensions.
2. If curve still missing, Press [ZOOM][3:Zoom Out] to zoom out so that you may be able to see a bigger range for the functions.
3. If necessary press [WINDOW] and set the Xmin, Xmax, Ymin,Ymax to values of your own.

Dimensions must obey the conditions: Xmin < Xmax, and Ymin < Ymax.

Zooming out on the graph


To zoom out click the Zoom button (top middle button) and then go to 3:Zoom Out. To go back to the standard go to zoom again and then scroll to 6:ZStandard.

Press ZOOM, then option 6 (ZStandard).

No line shows up am i doing it wrong?


Check your window settings (ZOOM, ZStandard gives the normal -10 to 10 for x and y). The Line(a,b,c,d) function draws a line from (a,b) to (c,d)
