So for this one we're looking for when the average growth rate is the least And so we're looking for one that rate is the lease. So those are key words there? Well, we know that and word problems that in terms of our equation if we had, like, a Y is equal to M. Iss was feverish. This isn't an X m s plus B, but if we were to split it up, it would roughly be you. And I'm explodes. Be many m explosive. He's basically okay. So then for this, we know that M is representative of our slow. So we always know this stuff is our rate. So then if we know that way, it's so bizarre rate and we want to know what the rate is the least That means when the slope is the smallest. Okay, so if you're looking for when the slope is the smallest, we could do like it here and clearly in the beginning, it's increasing very by a large amount of o tio. I expect this craft a little more extremes like this. So at the beginning and in the middle, it's going really fast. And then at the end. It's kind of tapering off. So at the very end between days sixty three eighty for the slope is gonna be the least to the rate is the least.
