Long before music was recorded digitally, people listened to music played on phonographs.
An antiques dealer models the value of a vintage phonograph using the function V(t) =
0.0412 - 3t + 395, where V(t) is the value in dollars and t is the number of years since
1925. The phonograph's value dropped as newer versions were introduced but then rose as
it became an antique.
