some years ago, mr. smith & mr jones bought a car on the same day. the value of both cars has decreased every year.
mr smith: function f can be used to determine the value of mr. smith's car:
f(x) = 23, 000b ˣ
where x is the time elapsed, in years since the car was bought
& y the value of mr. smith's car.
mr. jones: function g can be used to determine the value of mr. jones' car:
g(x) = a(0.82) ˣ
