So it looks like you have a function.
00:02
I'm just going to give you a function.
00:05
And let's say i have a function that looks like x squared plus 5x plus 2.
00:11
Now this is a parabola, and this will just be a generalization.
00:15
I know the y intercept is at 2.
00:18
And i know that the vertex for this parabola would end up being at negative b over 2a.
00:28
So that would be at negative 5 over 2.
00:33
So it's at negative 2 .5.
00:36
And i can plug in negative 2 .5 and find out what that gives me.
00:41
Negative 2 .5 squared minus 5 times 2 .5 plus 2 .2.
00:50
So it has a y intercept down, or the vertex is at the point negative 2.
00:59
And negative 4 .25.
01:01
So that parabola would do this.
01:08
And again, i don't know what your function is...
