The function A (x) = 28x – x2 where x = width, gives you the area of a dog pen in square
feet. What width gives you the maximum
area? What is the maximum area? Round to the
nearest tenth as necessary.
O width = 28 feet: area = 196 ft2
O width = 28 feet: area = 420 ft2
O width = 14 feet: area = 588 ft2
O width = 14 feet: area = 196 ft2
