This would probably have to do with the min and max window of your calculator. Press 2nd and Format(Zoom) and then change the the settings there.
Or
You can just press zoom and then 9 and it should work

When I graph system of linear equations and try to find an intersection point it says no sign change why?


The solve( function was not able to find the intersection point because it lies outside the graph range. The window dimensions are too narrow to contain that point. I suggest you restrict the graph to the quadrant where you suspect the solution to be (example first quadrant if appropriate) : take Xmin=0, Ymin =0 and choose Xmax and Ymax large enough to enclose the intersection point.

TI-84: trying to graph an equation and ERR: INVALID DIM shows up only PLOT 1 is highlighted Window XMax XMin Ymax and Ymin are correct Any ideas? Test tomorrow


You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

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.

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.

How to chang the size of the numbers


The title of the thread and the body of the question do not seem related. Or maybe I do not understand

A. Font size
If you want to change the font size in documents.
  1. Press the Home button
  2. Use arrows to highlight 8:system Info
  3. Press the Click button
  4. Select 2: System Setting and Press Click
  5. Use the tab key to highlight the Font size
  6. Use the down Arrow to unfold the menu and select Large
  7. Use the Tab repeatedly until you reach the OK button and Click or ENTER
  8. Accept the changes by pressing Yes.
Graph window ZOOM

If you have a graph and geometry document open (whether there is a graph or just the axes)
  1. Press the MENU button
  2. Select 4:Window
  3. Press Right Arrow to unfold the menu list
  4. Select the Zoom type
  • Window settings: You set your values
  • Zoom box: Select the corners of the box by moving cursor to desired position and press ENTER or Click.
  • Zoom In select center of graph and the graph will be redrawn
  • Zoom Out select the center
  • Zoom Standard :Standard window dimensions (default values)
  • Zoom Quadrant 1; restrict the graph to the first quadrant
  • Zoom Trig: When drawing trigonometric functions, dimensions are multiples of Pi.
  • Zoom Fit : The zoom is arranged to encompass all data.
  • Zoom square.
You can do certain manipulations by moving the cursor towards the axes. When the hand appears press Click/hand to grab. Pull out (away from an axis) or in (towards an axis). You can pull horizontally or vertically. The graph will react to the pull.

When graphing the calculator only allows me to graph on function. When typing in a new function the first function that was highlighted became unhighlighted and only the new function is highlighted now.


If you ran the dynamic graphing application called Transfrm you will only see one graph. It takes over the graphing from the native OS.
You will recognize it by the graph style at the left of the Y1=, etc. as in picture
2eac506.jpg4a76c70.jpg
As you can see, only one = is highlighted, meaning only Y1 will be drawn. To recover the native Y= screen, you must unload the Transfrm App from memory.

Here is how to do it.
Exit what you are doing and go to main calculator screen.
Press the Apps button.
Scroll down to find the Transfrm App
Highlight the : before the name and press ENTER.
The screen appears as on the second screen capture above
Press 1:Uninstall
This will unload it from memory and you will be able to draw multiples graphs.

There is the possibility that the failure to draw multiple graph has nothing to do with Transfrm. In that case it is most likely due to the Stat Plots being turned ON. Turn them OFF

Press [2nd][Y=] (STAT PLOT)
Select [4:PlotsOff] and press [ENTER]

I can't graph two functions at the same time (in y=) on a TI-84 Silver Edition. Can you help fix that?


Hello,
You bet I do, provided
1. there are no hardware problems I am not aware of;
2. that you are willing to follow my instructions.

Hope that helps.
