In this problem, we have x squared minus 2y is equal to 0.
00:07
Since only one of the terms is squared, we know that this will be a parabola.
00:14
Cleaning this up a little bit, i'm going to get negative 2y is equal to negative x squared, y is equal to positive 1 1 half x squared.
00:25
So in this case, we see because the x is squared, we know that this will be either up or down.
00:30
Since it's positive, we know it's going to be an upward -facing parabola.
00:36
Since nothing is being added or subtracted with the x's and the y's, again, i know my vertex is at zero, zero.

In this case, i will go, normally i go over one, up one, over two, up four, over three, up nine...
