2. What are good Web sites to use to confirm the information
3. How to look for alternative solutions or explanations

x: number of years after 1950

f (x): amount of vinyl sold.

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
