An airplanes altitude in feet during its descent for landing can be found using the function:f (x) = - 300x+300,000. where x represents the horizontal distance in miles from where the plain begins its descent. It then changes to g (x) = - 300x-30,500. which statement describes this change?

A:the airplane starts its descent from an altitude 500 feet higher.

B:the airplane starts its descent from an altitude 500 feet lower.

C:the airplane descends 500 feet per horizontal mile faster.

D:the airplane descends 500 feet per horizontal mile slower
