Graph the function.
(x)=-3x?

Step-by-step f(x)=-3x  

+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+ -3x%29+

 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = -3x). planation:

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
