You bought a car for $18,000. Each year the value of the car depreciates 20% . Write an Exponential function to represent how much the car depreciates each year. What would the value of the car be after 5 years? a f(x) = 18000(1+0.20)x ; $44,789.76
b f(x) = 18000(1 - 0.20)x ; $5,898.24
c f(x) = 18000(0.20)x ; $5.76
d f(x) = 18000(1+0.20)x ; $26,789.76
