Identify the sequence of transformations that will reflect a figure over the x−axis and then dilate it by a scale factor of 3.
a (x, y) > (x, −y); (x, > (3x, 3y)
b (x, > (x, −y); (x, > (3x, y)
c (x, > )(−x, y); (x, > (3x, 3y)
d (x, > (−x, y); (x, > (x, 3y)

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
