Apr 4, 2024 · Math 151 Sections 4.4: Concavity and Curve Sketching - Worksheet Solutions 1.Find the intervals where the functions below are concave up, concave down and find the inflection points. (a) f(x) = 1 x2 + 12 Solution. We need to find the second derivative off. We have f′(x) = − 1 (x2 + 12)2 (2x) = −2x(x2 + 12)−2,
5.3 Concavity and Inflection Points. Section 1: Determine the open intervals on which the graph s concave up or concave down. f (x) = 24 x2 + 12. f (x) = x2 + 1 x2 − 1. y = 2x − tan x π π , (− 2 ) Section 2: Find the inflection points and the open intervals of concavity.

Theorem 3. Let C R be an open interval. 1. f: C!R is concave i for any a;b;c2C, with a<b<c, f(b) f(a) b a f(c) f(b) c b; and, f(b) f(a) b a f(c) f(a) c a: For strict concavity, the inequalities are strict. 2. f: C!R is convex i for any a;b;c2C, with a<b<c, f(b) f(a) b a f(c) f(b) c b; and, f(b) f(a) b a f(c) f(a) c a:

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
