00:01
So we're given a graph of, i guess, these are projected promotional campaign deposits, whether we do their campaign or we don't.
00:11
Yeah, the project amount on it over the net, with and without.
00:13
So d1 is with the campaign, and d2 is without the campaign.
00:17
So they gave us this graph here.
00:19
So these are our projections.
00:20
They didn't tell us what the function is or anything.
00:23
So somehow we made these projections.
00:27
And basically we're saying that if we have an advertising campaign, promotional campaign, we're going to get more deposits than if we don't.
00:37
Now whether it's worth the money, it's another question.
00:40
So they ask us determine the signs of d1, d2 crime, d1 double prime, and d2 double prime on this interval here where we show.
00:49
So we can see that in both cases, the slope d prime, d1 or d1 or d2 prime, is greater than zero.
00:57
So in both cases we're increasing the number of deposits or the amount of deposits is increasing over time...
