Which expression is equivalent to 4 x 4 • −2 x -2 ? CLEAR CHECK −8 x -8 2 x 2 6 x 6 -8 • x

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
