We state these most recent observations formally as the definitions of the terms concave up and concave down. Concavity. Let \(f\) be a differentiable function on an interval \((a,b)\text{.}\)Moreover, the point (0, f(0)) will be an absolute minimum as well, since f(x) = x^2/(x^2 + 3) > 0,(AA) x !=0 on (-oo,oo) To determine where the function is concave up and where it's concave down, analyze the behavior of f^('') around the Inflection points, where f^('')=0. f^('') = -(18(x^2-1))/(x^2 + 3)^2=0 This implies that -18(x^2-1) = 0 ...Please see the explanation. Because the quadratic function is zero, when x = -1 and x = 3, it will have the factors: y = k(x + 1)(x - 3) where k is an unknown constant that one can use to force the quadratic to pass through a point with a non-zero y coordinate. If k > 0, then the quadratic opens upward. If k < 0, then the quadratic opens downward. I will multiply the factors: y = k(x^2 -2x - 3 ...

We conclude that we can determine the concavity of a function f f by looking at the second derivative of f f. In addition, we observe that a function f f can switch concavity (Figure 6). A function is graphed. The x-axis is unnumbered. The graph is a curve. The curve starts on the positive y-axis, moves upward concave up and ends in quadrant 1.

Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.If the second derivative is positive on a given interval, then the function will be concave up on the same interval. Likewise, if the second derivative is negative on a given interval, the function will be concave down on said interval. So, calculate the first derivative first - use the power rule. #d/dx(f(x)) = d/dx(2x^3 - 3x^2 - 36x-7)#Take x^2. It's concave up everywhere, but it is also decreasing until it gets to x=0. In fact if you use the f function from the video it is decreasing until it gets to x=5. f in the video is concave up everywhere, so just being concave up doesn't guarantee that its integral will also be concave up. I hope that helps.
