And now let's look at this middle graph. What would its derivative do? So over here, our slope is slightly negative, and then it becomes more and more and more and more and more negative. And so the derivative of this might look like it has to be slightly negative, but then it gets more and more and more and more negative as we approach that vertical asymptote. And in the right side of the vertical asymptote, our derivative is very positive here, and then it gets less and less and less and less and less and less positive. And so we start, our derivative would be very positive, and then it would get less and less and less and less positive. It looks like it might, the slope here might be asymptoting towards zero.
