Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

Every time i go to graph a parabola, i press"y=" and i type in my formula. but when i hit graph a message pops up that says "ERR: INVALID DIM". i dont know what to do. i think it might have something to do with the "Plot1", "Plot2", and "Plot3", being highlited. PLEASE HELP ME!!!!!!

Make sure all plots are off. to do this, 2nd-Y=. Highlight selection 4 (PlotsOff), and press enter twice. It should say Done.

Next, press the ZOOM button, and select number 6 (ZStandard). This will restore your window settings to default.

If those fail, press 2nd-+ to bring up the Memory menu. Press 7 (Reset), and select Default. This will not delete anything, it will just restore your settings.

Follow these steps: graph the parabola and after that **2nd** then **CALC** keypad. To find extreme value of the function select **3: min** or **4: max** options. Select the function and set left bound, right bound(using left and right arrows) by pressing **ENTER**. You can see images bellow for all these steps for the **y=-2x^2+5x+3**

1. step: graphing parabola

2. step: left or lower bound

3. step: right or upper bound

4.step: extreme value of the function

Enter the formula as an equality. Then, with the cursor on the formula, press 2ND [F6] to select Style. Choose "Above" or "Below" depending on which side of the graph you want shaded. Then press diamond [GRAPH] as usual to see the graph.

Sure it does! Did you ask it to graph?Here are some screen captures to help you find your way.

To draw functions (regular, parametric, polar, sequences) use the application graph: Highloghted on 1st screen capture. The second screen captures shows you the functions y=f(x). enter a legal expression and press F6 Draw. To set TYPE press the key under TYPE.

To draw conics (circles, parabolas, hyperbolas, and ellipses) use the CONiCS applications. (See 3rd screen ). On 4th capture the equation highlight is one for the parabola. y=x^2

Scroll down or up examining the small graphs. They will show you which equation form to choose.

For the circles

The actual graph depends on the constants (parameters) that are in the equation. Try playing with the dimensions of the window by zooming in or zooming out.

The most interesting part of the graph is the region near the maximum or minimum.

Here is a graph of the function y=X^2-5X 13 when drawn with standard window dimensions

Not very revealing. However if you press the Zoom key and select [2:ZoomIn] you see this (no changes) but the calculator is ready to accept your input concerning the new center of the graph.

At this stage, use the Arrow keys to move the center of the graph to another point as in the next screen capture.

Notice the new center as a sign on the screen and its coordinates at the bottom. By pressing [ENTER] you get this

If you keep Zooming in you may end up having something that does not look like a parabola anymore.

To summarize: Use the Zoom In or Zoom Out functions or find where the minimum/maximum is, center the graph on that point and modify the windows dimensions (Xmin, Xmax, Ymin, and Ymax) so as to get as much of the interesting part of the graph as possible.

The truth of the matter is that the curve drawn (the parabola) is the graph that you are seeking.

It is possible that you you mean by graph is the the set of axes. In that case you may have deactivated them. To reactivate them:

- Press [2nd][ZOOM] to access the (FORMAT).
- Press the DownArrow key 3 times to reach the line AxesON AxesOFF.
- Use the rightArrow to highlight AxesON and press [ENTER].
- Your graph will have the axes displayed.
