Practice Questions on Concavity
Question -1: Determine the intervals where function h(x)=x4-4×3+6×2-4x+1 is concave up and concave down.
Question -2:Find the intervals of concavity for the function p(X)=1/3 x3-2x2+3x+5.
Question -3:Analyze the concavity of the function q(x)=sin(x)-x on the interval [0,2π].
Concavity and Points of Inflection
Concavity and points of inflection are the key concepts and basic fundamentals of calculus and mathematical analysis. It provides an insight into how curves behave and the shape of the functions. Where concavity helps us to understand the curving of a function, determining whether it is concave upward or downward, the point of inflection determines the point where the concavity changes, i.e., where either curve transforms from concave upward to concave downward or concave to convex, and vice versa. These concepts are essential in various mathematical applications, including curve sketching, optimization problems , and the study of differential equations.
In this article, we’ll shed lights on the definitions, properties, and practical implications of concavity and points of inflection.
