And as we go from seven to 12, we're not adding any more area, but we're also not taking any away. So actually, g of seven all the way to g of 12 is going to be the same positive value because we're not adding any more value. When I say g of 12, g of 12 is going to be actually equal to g of seven because, once again, no added area right here, positive or negative. So let's see which of these choices match. For any x value in the interval from seven to 12, the value of f of x is zero. That is true, but that doesn't mean that we were positive. For example, before that interval, if our function did something like this, then we would have had negative area up to that point, and so these would be negative values.
