I'll get right down to it. I've got a TI Voyage 200, and I look at examples online for how to do things with it. My primary frustration at this point is that for finding the minimum and maximum values for a parabola, the example screenshots I see have x- and y-values displayed as well. Mine doesn't do this and I was hoping someone might be able to tell me if there is just a setting I have to change or if it's something worse. Any and all help will be much appreciated.
