And we're doing it all in terms of y. And in this case, we're going to integrate from y is equal to well, this is going to hit this y intercept right over here. So y is equal to negative 1. And let's go all the way to y is equal to 3. y is equal to 3 right over here. So from y equals negative 1 to y equals 3. So y equals negative 1 to y is equal to 3. And that's going to give us the volume of our upside down gum drop type looking thing.
