Neil started a stamp collection with 12 stamps. Every week, he adds 4 more stamps to the collection. Which function f represents the relationship between the number of stamps (s) and the number of weeks (w)?
s = f(w) = 12 + 4w
w = f(s) = 12s + 4
s = f(w) = 12 + 4s
w = f(s) = 12w + s
s = f(w) = s – 12

s = f(w) = 12 + 4s
w = f(s) = 12w + s
s = f(w) = s – 12
