Answer: f(x) = 18000(0.80^x)

Explanation:
The initial value is 18,000 because that is the value of the car when it was purchased. The equation can be derived by plugging these values into the formula for exponential growth: f(x) = a(1 + r)^x. This gives us f(x) = 18000(1 - 0.20)^x or f(x) = 18000(0.80^x).
