Which of the given statements involving extrema are true? If c is a critical number, then there is a local extreme value at c. Any function f that is defined and continuous on a closed interval [a,b] must have an absolute minimum. Any function fthat is defined on an open interval a,b must have an absolute maximum. If a function f fails to be differentiable a...
