A figura abaixo ilustra as localizações de alguns pontos no plano. João sai do ponto X, anda 20 m para a direita, 30 m para cima, 40 m para a direita e 10 m para baixo. Ao final do trajeto, João estará no ponto: (A) A (B) B (C) C (D) D

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
