What is the range of the function, f(x)=√(2x-4)

I am assuming that the 2x - 4 expression is under the square root sign, f(x) = √(2x - 4). The domain of this function is [2, ∞), since the square root of a negative number is not a real number. The range of f(x) is range is [0, ∞). This the is key to identifying the domain of the inverse function.

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
