there is going to be a point where A1 = A2
or A2-A1=0
yes, at the point of intersection there is no change. Before it, B is greater so population is 'gained', after it, D is greater so population is 'lost'
You think that before reaching that point, population was already lost, so it needs to be gained again to equal the initial population.
