I think I know the right answer. I just have an odd way of solving it, and I wanted someone to verify it. I got; vertex (0,0); focus (0,-4) directrix y=4; focal width=16

Yes! That is correct! How do you solve it?

I have an odd manner and it's complicated to explain, most of it I do in my head.

Ah. Okay. I'm all for weirdo methods! Always do those kinds of things at my school! I solve it by plotting the vertex, moving down the P (see formula), and moving up the p for the directrix, and then if the parabola is up and down, the line is horizontal, and vice versa! No problem! I LOVE this topic, so let me know if you have anymore questions with conics!
