Find the volume of the solid. All right, so region S, we see it right over here. In the last part, we already said that this function is f and this function is g. You could try out some values and think about how they behave, or you could get a sense that, hey, look, a fourth degree quadratic's gonna have these ups and downs like that, while the, something, well, this is, it has an x term, but then it has an exponential term right here. That might have more of a, kind of an upward trend, especially as x increases, and then an upward trend also as x becomes more and more negative, because this exponent is going to become positive. So you can think about them in different ways like that. But what's important is region S. And there's a couple things we have to think about. We have to think about the bounds of region S. We know that the upper bound of region S, x is equal to, we know x is equal to two here, but we don't know this value right over here.
