Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.If a function is concave downward, however, in a particular interval, it means that the tangents to its graph all lie above the curve itself on that interval. From this sketch, we can see that the slope of the tangent is now decreasing. And hence, we see that when a function is concaved downward, it's first derivative will be decreasing.•artition P Number - Determines open intervals where f(x) does not change sign • Critical Number - Really 0just a partition number for f (x), but in the domain of f ... → Intervals where f(x) is concave up or concave down: How Do We Use Them?

Example: f(x) = x 3 −4x, for x in the interval [−1,2]. Let us plot it, including the interval [−1,2]: Starting from −1 (the beginning of the interval [−1,2]):. at x = −1 the function is decreasing, it continues to decrease until about 1.2; it then increases from there, past x = 2 Without exact analysis we cannot pinpoint where the curve turns from decreasing to increasing, so let ... Recall that the first derivative of the curve C can be calculated by dy dx = dy/dt dx/dt. If we take the second derivative of C, then we can now calculate intervals where C is concave up or concave down. (1) d2y dx2 = d dx(dy dx) = d dt(dy dx) dx dt.
