HL Math Investigation

Is anybody else having trouble getting their calculator screenshot onto the computer? I have a TI-84 Plus, and when I do the screen capture, I just get a blank image. I even upgrated the operating system and such.

I found some very poor PC program to do the graphs here. But I'd much prefer getting my calculator in order.

I think this would also be a nice place to discuss other investigation related stuff such as what to write in the investigation.

I'm thinking its important to define in what cases the quartic will actually be a "W" shape. (f"(x) the discriminant has to be bigger than 0..?) And just provide some "W" shapes looking down, etc. And tryyy to present it in a general form.
