So this is, you could say, let me just write this, this is the change, I'll use delta for change, or let me just write it out. Change in population, change in population, population, but they don't want us to, they're not asking us for the change in population. They want us to know what is the town's population at t is equal to seven. So what you would want is, you would want what your population is at t equals two, plus the change in population from two to seven, to get you your population at seven. So they tell us the population at time t equals two, the town's population is 1,200 people. So if you want the population at t is equal to seven, it's going to be 1,200 plus how whatever the change in population, if you take the integral of the rate function, you are, and this is the rate of population, this integral is gonna give you the change in population from time t equals two to t equals seven. So we can see clearly that is choice D right over here.
