   Sep 12, 2024 · Concavity of Functions. A function f is concave up on an open interval if the graph resembles a 'U' shape or part of a smile. This behavior is represented by shading the graph in green. Conversely, a function f is concave down on an open interval if the graph resembles an upside-down 'U' shape or part of a frown.

   This notion is called the concavity of the function. Figure 4.34(a) shows a function f with a graph that curves upward. As x increases, the slope of the tangent line increases. Thus, since the derivative increases as x increases, f′ is an increasing function. We say this function f is concave up.

   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. Generally, a concave up curve has a shape resembling "∪" and a concave down curve has a shape resembling "∩" as shown in the figure below. Concave up.

   Dec 21, 2020 · If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points.

   How do you find the concavity of a function?

   • At these points, the sign of f" (x) may change from negative to positive or vice versa; if it changes, the point is an inflection point and the concavity of f (x) changes; if it does not change, then the concavity stays the same. Given these facts, we can now put everything together and use the second derivative of a function to find its concavity.

   Which function is concave down over the interval?

   • Since f′′(x) < 0 for x > a, the function f is concave down over the interval (a, ∞). The point ⎛⎝a, f(a)⎞⎠ is an inflection point of f. For the function f(x) = x3 − 6x2 + 9x + 30, determine all intervals where f is concave up and all intervals where f is concave down. List all inflection points for f. Use a graphing utility to confirm your results.

   When a function f is concave up if f′ is increasing?

   • By definition, a function f is concave up if f′ is increasing. From Corollary 3, we know that if f′ is a differentiable function, then f′ is increasing if its derivative f′′(x) > 0. Therefore, a function f that is twice differentiable is concave up when f′′(x) > 0. Similarly, a function f is concave down if f′ is decreasing.
