Example 11

These questions deal with characteristics of the first and second derivatives of a function at and near a minimum value.

a. Below is a graph of a function f with a minimum at x = x0. Determine the sign of the derivative f' at each labelled x-value.

b. Assume f is defined and twice differentiable on the whole real line. Around a minimum of the function f, is f concave up or concave down?

Example 12

These questions deal with characteristics of the first and second derivatives of a function at and near a maximum value.
