Hi, so today we're going to try to find the equation for the problem with the information that we were given.
00:07
So first i'm going to write down the information that we were given.
00:10
We were given that the focus is at negative to zero and that the vertex is at the origin, so it's just going to be at zero.
00:27
Now that we got that out of the way, we're going to now draw out the graph because then we'll get a better idea of how this looks like and we'll be able to understand.
00:36
How to approach and finding what the equation will look like.
00:44
So we know that the focus is at negative to 0, so it'll be right here, and we know the vertex is at the origin, or 0 ,0, so it'll be right here.
00:54
Now, the graph is going to open up towards where the focus is, which is on the left side of the vertex, on the left side.
01:05
So since it's on the left side of the vertex, it's going to open up towards the left since the focus is on the left side of the vertex.
01:13
Now that we understand that, we know what our basic equation format will be.
01:19
It's going to look like y minus k squared is equivalent to 4p x minus h.
01:26
These are just a general format we work with when we are doing parabola equations.
01:33
So now that we got the basic format for parabola equations...
