In all probability, someone used the Transfrm Application before. The problem is that it lingers in memory and has to be unloaded from RAM.
To do so

Press the APPS button.
Scroll Up or down to reach the Transfrm APP.
Select it and press ENTER.
In the subsequent screen, press the number that corresponds to the UNINSTALL option.
Validate the selection by pressing the ENTER button.
Go back to your Y= Editor and enter up to 10 functions, then press the GRAPH key.
Graphs should know display correctly.

I can only display a graph of one equation at a time (from the Y= screen). Is there a way to change this?

Try pressing enter after you put in the first equation, then put in the second equation.

How do I get the calculator to graph an equation like y=-3x-1

Press Y= (the first function key on the top row). On the line beginning Y1=, put in the right hand side of the equation: 3 ALPHA [X] - 1

Press GRAPH (the last function key on the top row) and you'll see the graph. If you want to look at different parts of the graph, press WINDOW and change the window settings.

I'm graphing a quadratic equation, I have all my info put into the stat area and nothing in the Y= area. When I graph it the points are small boxes, there is no graph line and it won't allow me to do any...

If you're doing a stat plot, you're plotting a discrete set of points. The calculator doesn't interpolate between the data points.

If you want to graph a quadratic equation, then do so. Enter it in as a Y= equation and plot it as such. This will not only connect the points (unless you tell it not to), but will also allow you to do things like trace.

Graphing an equation

Press the Y= key to invoke the Y= editor. Enter in your equation.

Press the WINDOW key to set the window parameters.

Press the GRAPH key to have the calculator graph the equation.

For more details and options, see the "Function Graphing" chapter in the Guidebook.

My calculator will only graph one graph at a time.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!

Solver not working properly

try a simple equation like x^2-1 which should come out with x = 1,-1

no sign change would indicate that the graph of the curve never crosses the x axis, if you graphed the above equation and calculated the zeros, it would come out with -1, 1 which it should, but if you put in x^2+1, the graph would never cross and therefore have no sign change from pos to neg or vice versa, the left-rt are the left and right bounds or the lower and upper bounds which was corrected in later calculators, Please let me know the outcome of graphing both of the above equations and then putting them in the solver. you could also use the quadratic equation to prove the answers if you liked, hope this helps

Graphing

The first solution will allow you to watch your calculator graph two equations simultaneously rather than finishing one before graphing the next; it won't solve the problem of having the calculator unselect one equation when you select a second. To fix that problem, try the following:

In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.

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