The value of a car decreases the older it gets. Matthew bought a new car for \$14,000. Every year, the value of his car decreases by 5%. Write a function formula f(x) for the value of Matthew's car where x represents the number of years since he bought it.

OpenStudy (anonymous):

f(x)=14,000 minus (1-.05)^x

OpenStudy (anonymous):

should be right, its been a long time since ive worked that formula

jimthompson5910 (jim_thompson5910):

Formula should be \[\large y=14000(0.95)^{x}\]

OpenStudy (anonymous):

times not minus sorry. hes right

OpenStudy (anonymous):

but write f(x) not y because it is a function

jimthompson5910 (jim_thompson5910):

good point, forgot about that piece \[\large f(x)=14000(0.95)^x\]
