The current path of a submarine can be represented by a quadratic function, where x represents the horizontal distance traveled from the base, and D(x) represents its depth in the water. The submarine surfaces at 5 miles out from the base and then again after having traveled 15 miles farther. Which of the following equations can be used to represent the path of the submarine?

D(x) = -0.02(x - 5)(x - 15)

D(x) = 0.02(x - 5)(x - 20)

D(x) = -0.02(x - 5)(x - 20)

D(x) = 0.02(x - 5)(x - 15)
