Okay, because it says area, okay, we really need to know which graph is on top and which graph is on the bottom.
00:08
So i'm going to start with this line, okay, this one.
00:14
When i put negative 5 for x, i get 100 plus 10, 1, 210.
00:21
So this is 210.
00:23
And then when i put 2, negative 40 plus 110 is 70.
00:30
So this is that graph, okay.
00:33
This is y is equal to negative 20x plus 10, 110, between negative 5 and 2.
00:40
And then this, the other one is, this one is a parabola.
00:46
Parabola with a vertex 14, and it's opening down, okay, when x equals 2, y is 10, right, 14 minus 4, so it's like this.
01:01
And then it's going like this, opening down all the way.
01:05
And what is this value when x is negative 5, 14 minus 25, negative 11...
