Answer C:  

Step-by-step explanation:

Notice that all the functions look like x plus a constant in the numerator, and x minus the same constant in the denominator.

So we can do a general analysis finding the inverse of a function of the form:

and finding which value of "a" will make

To find the inverse we need to solve for "x" in the equivalent equation:

Then, we see that if , then the expression for

Then the function that verifies this condition is:

the two may have that, even a breakdown is probably offered

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
