All right, now let's do this together. The way I'm going to tackle it is I'm going to try to sketch what we can about the derivatives of each of these graphs, or each of the functions represented by these graphs. So in this first graph here in this orange color, we can see that the slope is quite positive here, but then it becomes less and less and less positive up until this point where the slope is going to be zero, and then it becomes more and more and more and more negative. So the derivative of this curve right over here, or the function represented by this curve, it's gonna start off reasonably positive right over there. At this point, the derivative is gonna cross zero because our derivative is zero there, slope of the tangent line. And then it's gonna get more and more negative, or at least over the interval that we see. So it might look, I don't know, something like this.
