I transfered classes and they use graphing calculators. I've never used the graphing functions on mine. We were supposed to graph exponetial functions. Help?

1. Kellie, there are many makes and models of graphing calculators, Texas Instrument, Casio, HP, etc
each one having its own method.

Your best bet is to have somebody show you how, or look at the manual. They should have examples.
Another idea would be to find the webpage for your model of calculator, they might have instructions or manuals you can print out.
