And we're going to evaluate that at five and at negative three and we're gonna find the difference between these two. So what we have right over here, evaluating the antiderivative at our upper bound, that is going to be four x five. And then from that, we're going to subtract evaluating our antiderivative at the lower bound. So that's four x negative three. Four x negative three. And what is that going to be equal to? So this is 20 and then minus negative 12.
