We're going to evaluate that at the bounds and take the difference. So we're going to evaluate that at negative two and then subtract from that this evaluated at negative one. And let me do those in two different colors just so we can see what's going on. So we're gonna evaluate it at negative two and we're going to evaluate it at negative one. So let's first evaluate it at negative two. So this is going to be equal to, this is going to be equal to, when you evaluate it at negative two, it's going to be negative eight, negative eight times x to the negative two, so negative two to the negative two power, minus negative two, and from that we're going to subtract it, evaluate it at negative one. So it's going to be negative eight times negative one to the negative two power, minus negative one.
