- Concavity describes whether a graph opens upward (concave up) or downward (concave down). It indicates whether the graph is curving upwards like an "U" shape or downwards like an "n" shape.

How do you find concavity in a graph?
Concavity refers to the direction of the curvature of a function's graph. It indicates whether the graph is bending upwards (concave up) or downwards (concave down) and is closely related to the second derivative of the function.
Nov 21, 2023 · The rate of change of a function's derivative is called concavity. This is also known as the concavity definition. Concavity is an important property of the second...
Review your knowledge of concavity of functions and how we use differential calculus to analyze it.
- You have two functions f and g, where f''>0 and g''>0. If you take the second derivative of f+g, you get f''+g'', which is positive. So their sum i...
- In order for 𝑓(𝑥) to be concave up, in some interval, 𝑓 ''(𝑥) has to be greater than or equal to 0 (i.e. non-negative) for all 𝑥 in that inter...
- In general, no. Points where f"(x)= 0 are specifically called inflection points. But in the example provided, -2 is also a critical point (Observe...
- Product rule: d/dx[f(x)*g(x)] = f'(x)g(x) + f(x)g'(x) f(x) = (x-1)³ and g(x) = x
convex lens: A lens having at least one convex surface, such that light passing through it, may be brought to a focus. concave lens: A lens having at least one concave surface, such that light rays passing through it bend away from its optical axis.

Jun 15, 2022 · Concavity describes the behavior of the slope of the tangent line of a function such that concavity is positive if the slope is increasing, negative if the slope is decreasing, and zero if the slope is constant.
Concavity of a Function Definition: Indicates the direction of the curve's bend; concave up like a cup and concave down like a cap, with changes marked by inflection points. How to Determine Concavity: Analyse the function's second derivative; positive indicates concave up, negative indicates concave down.
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.
