Second Derivative and Concavity. Graphically, a function is concave up if its graph is curved with the opening upward (Figure \(\PageIndex{1a}\)). Similarly, a function is concave down if its graph opens downward (Figure \(\PageIndex{1b}\)). Figure \(\PageIndex{1}\) This figure shows the concavity of a function at several points. Example 3.5.1: curve sketching. Use Key Idea 4 to sketch f(x) = 3x3 − 10x2 + 7x + 5. Solution. The domain of f is the entire real line; there are no values x for which f(x) is not defined. Find the critical values of f. We compute f ′ (x) = 9x2 − 20x + 7. Use the Quadratic Formula to find the roots of f ′:The slope forms downward curves, similar to how concave down graphs look. Related terms. Inflection Point: An inflection point is a point on the graph where the concavity changes from concave up to concave down or vice versa. Decreasing Function: A decreasing function is one in which the y-values decrease as x-values increase.The point at (negative 1, 0.7), where the graph changes from moving downward with increasing steepness to downward with decreasing steepness is the inflection point. The part of the curve to the left of this point is concave down, where the curve moves upward with decreasing steepness then downward with increasing steepness.The graph of a concave function is a curve that is bowed downward, and it looks like a frown. For example, the function f(x) = -x^2 is a concave function because its second derivative is -2, which is negative. The concavity of the graph of a function refers to the curvature of the graph over an interval; this curvature is described as being concave up or concave down.
