Since f is increasing on the interval [ − 2, 5] , we know g is concave up on that interval. And since f is decreasing on the interval [ 5, 13] , we know g is concave down on that interval. g changes concavity at x = 5 , so it has an inflection point there. This is the graph of f . Let g ( x) = ∫ 0 x f ( t) d t . For $$$ x\gt0 $$$, $$$ f^{\prime\prime}(x)=6x\gt0 $$$ and the curve is concave up. This confirms that $$$ x=0 $$$ is an inflection point where the concavity changes from down to up. Concavity. Concavity describes the shape of the curve of a function and how it bends. The curve can be concave up (convex down), concave down (convex up), or neither. Fact. Given the function \ (f\left ( x \right)\) then, If \ (f''\left ( x \right) > 0\) for all \ (x\) in some interval \ (I\) then \ (f\left ( x \right)\) is concave up on \ (I\).
