Sal introduces the concept of concavity, what it means for a graph to be "concave up" or "concave down," and how this relates to the second derivative of a f. Well following the idea of the single variable second derivative test, what you might do is take the second partial derivatives of our function and see how that might influence concavity.

The Differential Calculus Math Mission is a set of skills on Khan Academy. Take notes as you watch these videos. The derivative of the quadratic function is linear, so the second derivative function of a cubic polynomial is linear (degree 1). Suppose is a function of that is twice differentiable at a stationary point . The Second Derivative Test (for Local Extrema) In addition to the first derivative test, the second derivative can also be used to determine if and where a function has a local minimum or local maximum. f (x) = 12+6x2 −x3 f ( x) = 12 + 6 x 2 − x 3 Solution.
