The farmer has 800 meters of fencing and does not need to enclose the river side of the plot. River יר X Let æ be the length of the enclosed land and y be the width, both measured in meters, as shown. Which two of the following functions would have a critical point at the x or y-value that maximizes the enclosed area?
