The function f(x) = 17, 400 * (0.85) ^ x represents the values of a certain type of car x years after it is purchased. Xavier states that the decay rate of the value of the car is 85%. Which accurately describes Xavier's statement?
(1 point)
• Xavier correctly determined the decay rate of the value of the car.
• Xavier should have subtracted 0.85 from 1 to determine a decay rate of 15%.
• Xavier should have added 0.85 to 1 to determine a decay rate of 1.85%.
• Xavier should have divided 1 by 0.85 to determine a decay rate of 1.18%.
