Apoint undergoes two transformations. the x-coordinate's sign changes and the y-coordinate increases. what were the transformations? the point was reflected over the y-axis and translated down. the point was reflected over the x-axis and translated to the right. the point was reflected over the y-axis and translated up. the point was reflected over the x-axis and translated to the left. (repost) (69 points)

The point was reflected over the y-axis and translated up.

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
