So it's just two plus zero, which is equal to two. So g of negative three is equal to two. And we're done with part a. And the trickiest part of this is just realizing the bounds of integration. That you might be tempted to say, oh, the integral between zero and negative three, that's just this area over here, because we're going between zero and negative three. But you gotta realize that we actually have to swap them and make them negative if you really want to consider this area right over here. That this integral is going to be the negative of this area.
