All right, so we have a sideways parabola, meaning that my general formata of this is going to be y minus k squared is equal to 4p times x minus h.
00:13
H and k are going to be the 3 in the 1.
00:16
So i'm going to have y minus 1 squared is equal to 4p times x minus 3.
00:24
So now i need to find what 4p is going to equal to.
00:29
And i guess i don't even have to do the 4p because that's going to.
00:31
It's going to be the focus, but i don't need that here.
00:33
I'm just going to call it a.
00:37
Let's put it there.
00:39
So then i'm going to pick another set of points here, like, for example, 0 -0 and see what happens when i put those in.
00:45
So we've got 0 -1 squared as equal to a times 0 -3.
00:51
That's going to be negative 1 square, which is 1, and then a times a negative 3...
