How to find the vertex of a parabola from the vertex form

[00:00:00]This is how you find the vertex of a parabola when we are given the vertex form. So for the first one, we see that we have plus three here. But we really have to do the opposite of that because the formula right here is a h. So we have -3 here. But on the outside it is just what it is. You have -4. So the vertex is at -3,4.

[00:00:23]Now for the second one, we have -6 here.

[00:00:26]But do the opposite. So you have positive six and on the outside the k value is seven. So the vertex is six comma 7. Lastly it's just x squar. So what's h technically zero. And then this right here is the k. So 0 comma9. That's it.
