So f of 1, that's the height here, plus f of 2, all of that over 2, and then we're going to multiply it times our delta x. Actually, let me do that in that same red color to show you that this is the area of that first trapezoid. So times delta x. And as you see right over here, if you look at it, the f of 1 is just going to be 0, so you're going to have f of 2 times, so it's going to be this height times this base times 1 half, which is just the area of a triangle. But let's look at the second trapezoid, trapezoid 2. Right over here. What is its area going to be?
