A local minimum occurs when the graph of a continuous function changes from [Select] A real number x in the domain of f such that f'(x) = 0 or f'(x) does not exist is called a [Select] of f.

Find a function for which f'(x) exists for all real numbers but f"(x) doesn't exist for all real numbers

Sketch the graph of a function f such that: f'(-2) > 0, f'(0) = 0, f(2) < 0, and f(0) = 0 5 1Y 4 3 -5 -4 -3 -2 1 1 1 2 4 -2 -3 -4 -5
