The basic way of attacking this problem is the fact that you have a negative 200x squared right here.
00:07
So if you're trying to graph this, what's going to happen is like the curve will go up and then come back down because it's a negative parabola.
00:19
Sorry, a negative a squared value.
00:22
So the max will be up here.
00:23
And then you have this plus 92 ,000 x and then another plus number.
00:32
Well, it's actually a minus.
00:33
So my graph is very off 8 -4 -0 -0 -0 -0.
00:41
So a better graph instead of what i have would look more like this.
00:46
But anyway, in order to find that max, what you want to do is x equals negative b over 2a, and the a value is negative 200, and the b value is this 92 ,000 number.

Let me double check out of the right numbers...
