The number line in Figure 3.4.5 illustrates the process of determining concavity; Figure 3.4.6 shows a graph of f and f ″, confirming our results. Notice how f is concave down precisely when f ″ (x) < 0 and concave up when f ″ (x) > 0.First, recall that the area of a trapezoid with a height of h and bases of length b1 and b2 is given by Area = 1 2h(b1 + b2). We see that the first trapezoid has a height Δx and parallel bases of length f(x0) and f(x1). Thus, the area of the first trapezoid in Figure 2.5.2 is. 1 2Δx (f(x0) + f(x1)).Estimate from the graph shown the intervals on which the function is concave down and concave up. On the far left, the graph is decreasing but concave up, since it is bending upwards. It begins increasing at \(x = -2\), but it continues to bend upwards until about \(x = -1\).A critical point is when the derivative equals 0. And while it is always negative where you indicated, the derivative itself is increasing at one point. A much easier example to see this is -x^2. if this were the derivative of something, this also has a critical point at (0,0).This derivative is increasing in value, which means that the second derivative over an interval where we are concave upwards must be greater than 0. If the second derivative is greater than 0, that means that the first derivative is increasing, which means that the slope is increasing. We are in a concave upward interval.Now that we know the second derivative, we can calculate the points of inflection to determine the intervals for concavity: f ''(x) = 0 = 6 −2x. 2x = 6. x = 3. We only have one inflection point, so we just need to determine if the function is concave up or down on either side of the function: f ''(2) = 6 −2(2)For a quadratic function f (x) = ax2 +bx + c, if a > 0, then f is concave upward everywhere, if a < 0, then f is concave downward everywhere.
