Find all critical numbers of the function f x x 72x Then use the second derivative test on each critical number to determine whether it leads to a local maximum or minimum Select the correct choice below and if necessary fill in the answer box es to complete your choice OA The critical number s is are at x There is no local maximum and no local minimum Type an integer or a simplified fraction Use a comma to separate answers as needed OB The critical number s is are at x There is a local maximum at x There is no local minimum Type an integer or a simplified fraction Use a comma to separate answers as needed OC The critical number s is are at x There is no local maximum There is a local minimum at x Type an integer or a simplified fraction Use a comma to separate answers as needed OD The critical number s is are at x There is a local maximum at x There is a local minimum at x Type an integer or a simplified fraction Use a comma to separate answers as needed OE There are no critical numbers
