I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 PLEASE SEE ATTACHED IMAGE.

 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
