And so let's evaluate each of these. And you might even be able to just evaluate these with a little bit of triangle areas, but let's just do this analytically or algebraically. And so what's the antiderivative of negative x? Well, that's negative x squared over two, and then we have the negative two, or so the antiderivative is negative two x. We're gonna evaluate that at negative, at negative two and negative four. And so that part is going to be what? Negative two squared, so it's the negative of negative two squared.
