WebFeb 24, 2024 · Determining whether a function is concave up or down can be accomplished algebraically by following these steps: Step 1: Find the second derivative. Step 2: Set the second derivative equal to 0 0 ... WebConcavity relates to the rate of change of a function's derivative. A function f f is concave up (or upwards) where the derivative f' f ′ is increasing. This is equivalent to the derivative of f' f ′, which is f'' f ′′, being positive. Similarly, f f is concave down (or downwards) …
