But here, the function is below the x-axis. And so what we can do is we can figure out this area, just knowing what we know about geometry, and then we have to realize that this is going to be a negative value for the definite integral because our function is below the x-axis. So what's the area here? Well, there's a couple of ways to think about it. We could split it up into a few shapes. So you could just view it as a trapezoid, or you could just split it up into a rectangle and two triangles. So if you split it up like this, this triangle right over here has an area of one times two times 1 1⁄2.
