So this first part of our expression, the definite integral from negative four to negative two of f of x, dx, we're going from x equals negative four to x equals negative two. And so this would evaluate as this area between our curve and our x-axis, but it would be the negative of that area because our curve is below the x-axis. And we could try to estimate it based on the information they've given us, but they haven't given us exactly that value. But we also need to figure out this right over here. And here we're going from x equals negative two to zero of f of x, d of x, so that's gonna be this area. So if you're looking at the sum of these two definite integrals, and notice the upper bound here is the lower bound here, you're really thinking about this is really going to be the same thing as this is equal to the definite integral going from x equals negative four all the way to x equals zero of f of x, dx. And this is indeed one of our integration properties.
