17. So you bought a new boat for $10,000, you noticed that the value of the boat will decrease
linearly for the next 10 years, until it is worth $0.
Which of the following models describe the value
of the boat as a function of the number of years
you've owned the boat?
a)f(x) = 1,000x – 10,000
b)f(x) = 10,000x – 1,000
cf(x) = -1.000x – 10.000
D f(x)= -1000x+10000
