A pond in Luke's neighborhood has a depth of 81.6 inches. During the dry season, the pond loses an average of 0.02 inches of water each day. Luke wrote the function below to represent the depth of the pond in inches x days after the dry season begins. Explain Luke's error and rewrite the function correctly.

• f(x) = -0.02(x + 81.6)

• f(x) = -0.02x + 81.6

• f(x) = -0.02x - 81.6

• f(x) = -0.02(x - 81.6)
