So it will be nice to swap those bounds so we can truly view it as the area of the region under f of t above the t-axis between those two bounds. And so when you swap the bounds, this is going to be equal to negative definite integral from negative two, negative two to zero of f of t dt. And now what we have right over here, what I'm squaring off in magenta, this is the area under the curve f between negative two and zero. So between negative two and zero. So that is this area right over here that we care about. Now what is that going to be? Well, you could, there's a bunch of different ways that you could do this.
