Or if you viewed this as negative x to the zero power, because that's what one is, well, it's the same thing. You increase the exponent by one to get x to the first power. And then you divide by one. And so, I mean, you could view it as that right over there. But either way, you get to negative or minus x. And so now we want to evaluate that. We're going to evaluate that at the bounds and take the difference.
