This quadratic, first thing i'm going to do is a, b, and c.
00:05
Now, be careful that b value is zero.
00:09
So this graph opens up because my a value is greater than zero or positive.
00:15
Next, i'm going to do the axis of symmetry.
00:18
So i'm going to use the opposite of b over 2a.
00:22
That's 0 over 10, which is 0.
00:27
I can grab that.
00:30
Next, i'm going to plug that 0 into my original.
00:33
To get the y coordinate of my vertex.
00:38
That's going to be 2.
00:40
So my vertex is it 0 2, which is right there.
00:46
Now, y intercept is really already done for you, because you already have a point on the y -axis...
