And so the integral from zero to seven, if this was a t-axis, and once again, t is just kind of a placeholder variable to help us keep this x up here, but we're really talking about this area right over here. And because from zero to seven, this function is above the x-axis, this is going to be a positive area. This is a positive area. 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.
