The first ferris wheel ever built was created by Gale Ferris in 1893. The following chart shows the height of carts at
various points of time.
Time (min) 0 2.25 4.5 | 6.75 9
Height (meters) 8 46 84 46 8
a) Write the regression equation that best describes the
height of a cart on the ferris wheel after t minutes.
b) What is the period of the function?
c) How high is the ferris wheel off the ground?

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
