If f(x) = -3x - 2
find f(3)

f ( − 3 ) = 9

Step-by-step explanation:

f ( x ) = x 2  

To find f(-3) replace  x  in the function by  − 3  

Therefore:  

f ( − 3 ) = ( − 3 ) 2 = − 1 2 × 3 2 = 1 × 9 = 9

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
