How to Find Local Extrema with the Second Derivative Test

WebThe second derivative is the concavity of a function, and the second derivative test is used to determine if the critical points (from the first derivative test) are a local maximum or local minimum. If the second derivative at a critical point is negative, then it is a local maximum, and if the second derivative at a critical point is positive then it is a local minimum.
