TI-89 Titanium Help (graphing quadratic functions)

In summary, the speaker is asking if there is a way to input values within a specific range into their calculator. They give an example of wanting to graph y=2x between x=-3 and x=3 and only display the graph within that range. The expert responds by suggesting using the WIND (window) option on a TI86 calculator to set the xMin and xMax values to -3 and 3 respectively. This will limit the displayed graph to the specified range.

Is there a way to input values within a certain range into my calculator? For example, if I come across something like this:

"Draw a curve of y=2x between the values x=+3 and x=-3. From the curve write down the following values:

etc, etc, etc"

How can I make it graphic w/in a certain range?

I can tell you how to do it on a TI86, which should be quite similar to the 89. Graph as normal, and then use the WIND(window) option to set xMin = -3 and xMax = 3. It will then only display the graph in that range.
