Find all critical numbers of y=5x-x+2, then determine the local minimum and maximum points by using a graph. a.) Critical number: x = 0 (0,2) is a local minimum. b.) Critical number: x = 0, x = 8 (0,2) is a local minimum, and (8, -10) is a local maximum. c.) Critical numbers: x = 0, x = 2 (0,2) is a local minimum, and (2, 33/4+2) is a local maximum. d.) Critical number: x = 2 (2, 33/4+2) is a local maximum. Find all critical numbers of y=5x-x+2, then determine the local minimum and maximum points by using a graph. a.)
