Step-by-step explanation:
Part A:
car 1 => exponential function
car 2=> linear function
Part B:
car 1 => the function f(x) = 45,000 • (0.9)^x
car 2= > the function f(x) = 45,000 - (3,000)x
Part C:
after 13 years, the value of :
car 1 => 45,000 • (0.9)^13 = $ 11,438.40
car 2=> 45,000 - (3,000)(13) = $ 6,000
the difference is = 11,438.40 - 6,000
= $ 5,438.40
its better to Belinda to purchase car 1.
