Example 5: a particle moves from right to left along the parabola in such a way that its x-coordinate (in meters) decreases at the rate of 8 m/sec. how fast is the angle of inclination of the line joining the particle to the origin changing when x=-4

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
