Question

10. The value of a car, in dollars, x years after its purchase is represented by the function f(x) = 8000(0.55) x . What is the average decrease in value per year between years 1 and 2? (Round to the nearest whole number)

Answer 1

f(1)=8000x0.55x1=4400
f(2)=8000x0.55x2=8800
(8800-4400)/2=2200
