- 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.

Dec 21, 2020 · When the graph is concave up, the critical point represents a local minimum; when the graph is concave down, the critical point represents a local maximum. We have been learning how the first and second derivatives of a function relate information about the graph of that function.
f(b)(c a) f(a)(c b) + f(c)(b a); which (since c a > 0) holds i. f(b)baf(a) +aaf(c):Take = (c b)=(c a) 2 (0; 1) and verify. that, indeed, b = a + (1 )c. Then the last inequal. ty holds since f is concave. Conversely, the preceding argument shows that if the rst inequality in (1) holds then f is.

What is concavity? The state or quality of being concave. Concave up: Concave down: If a function is concave up (like a parabola), what is 𝑓 ñ is doing. If 𝑓 is concave up, then 𝑓 ñ is increasing. If 𝑓 is concave down, then 𝑓 ñ is decreasing. This leads us to the following… 𝑓 ñ ñ P0 means 𝑓 is concave up. 𝑓 ñ ñ
