   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.

   If a function changes from concave upward to concave downward or vice versa around a point, it is called a point of inflection of the function. In determining intervals where a function is concave upward or concave downward, you first find domain values where f″ (x) = 0 or f″ (x) does not exist.

   Why do we need to know where a graph is concave?

   • 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 know if a function is concave upward?

   • A function is said to be concave upward on an interval if f″ (x) > 0 at each point in the interval and concave downward on an interval if f″ (x) < 0 at each point in the interval. If a function changes from concave upward to concave downward or vice versa around a point, it is called a point of inflection of the function.

   What does a concave function look like?

   • Likewise, a function that is concave downward on an interval looks like a portion of a parabola that opens downward. If the graph of a function is linear on some interval in its domain, its second derivative will be zero, and it is said to have no concavity on that interval.

   What if a graph of a function has no concavity?

   • If the graph of a function is linear on some interval in its domain, its second derivative will be zero, and it is said to have no concavity on that interval. Example 1: Determine the concavity of f (x) = x3 − 6 x2 −12 x + 2 and identify any points of inflection of f (x). Because f (x) is a polynomial function, its domain is all real numbers.

   Is f g a concave function?

   • where the first inequality holds since f is concave and g increasing, and the second inequility follows from g being concave. We have thus proved that Thus, (f ◦ g) is a concave function. (with a similar proof for convexity.) Remark 10. An increasing transformation of a concave (convex) function is not necessarily concave (convex).

   Dec 21, 2020 · 1. A curve that is shaped like this is called concave up. Figure 5.4.1 5.4. 1: f′′(a)> 0 f ″ (a)> 0: f′(a) f ′ (a) positive and increasing, f′(a) f ′ (a) negative and increasing. Now suppose that f′′(a) <0 f ″ (a) <0. This means that near x = a x = a, f′ f ′ is decreasing.
