The elevation at ground level is 0 feet. An elevator starts 90 ft below ground level. After traveling for 15 seconds the elevator is 20 feet below ground level. Which statement describes the elevators rates of change in the elevation during this 15-second interval?

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
