Salut, j'ai un examen de math qu'est-ce que je peux écrire sur la feuille aide mémoire? Mon examen ça va être sur l'algèbre, fonctions et système d'équations et inéquations pour que ça peut vraiment m'aider pendant l'examen!!

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
