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. I don't know if it's a line or not, it might be some type of a curve, but it would definitely have a trend something like that. Now we can immediately tell that this blue graph is not the derivative of this orange graph. Its trend is opposite.
