I'm trying to follow along on some of the examples using a TI-84 plus calculator, and I can't get the graphs to come out the same as the examples. Only way I know how to graph quadratic equations is pressing "y=", filling out the equation, and hitting graph. Not sure what to search to even figure out other ways, if someone knows a good resource to help figure out what I'm even doing, that would be much appreciated. Thanks!
