90-degree angle  

as you can see, there is clearly a 90 degree right next to it, but that doesn't tell us anything, because it has symmetry with the 3 right next to it, all that is different is that it has a longer x-axis, which will not affect our answer.

Hope this helps!    

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
