Question 1155852: A car is sold for $20,000. After one year, the value of the car is $13,000. Write an exponential function y to determine the value of the car after x years if the rate of decrease is the same each year.
y=20000(1-0.65)^x was my best guess, but that seems to be wrong. Answer by ikleyn(52788) (Show Source):
