So over here, our slope is quite negative, and it becomes less and less and less negative until we go right over here where our slope is zero. So our derivative would intersect the x-axis right over there. It would start out negative, and it would become less and less and less negative, and at this point, it crosses the x-axis, and then it becomes more and more positive. So we see here, our derivative becomes more and more positive, but then right around here, it seems like it's getting less positive again. So it might look something like this, where over here, it's becoming less positive again. Less positive, less positive, less positive. Right over here, our derivative would be zero.
