- Concavity describes the direction in which a curve bends, specifically whether it opens upwards or downwards. A function is said to be concave up on an interval if its graph lies above its tangent lines, indicating that the slope of the tangent lines is increasing.

Definition. Concavity describes the direction in which a curve bends, specifically whether it opens upwards or downwards. A function is said to be concave up on an interval if its graph lies above its tangent lines, indicating that the slope of the tangent lines is increasing.

Jun 9, 2023 · A concavity calculator is an online tool used to determine the nature of a function—whether it's concave up, concave down, or experiencing an inflection point at a given interval. The calculator uses the principles of the second derivative test in calculus to make this determination.
Inflection points are points on the graph of a function where the concavity of the curve changes. In mathematical terms, for a function f(x), an inflection point occurs at x = a if the second derivative of the function, i.e. f′′(x), changes sign at that point. This can be the case if f′′(a) = 0 or f′′(x) does not exist.
