study the function table below

vases flowers
4 12
7 21
8 24
11 33
v f

which expression could be used to find the number of flowers (f) in (v) vases?

my answer is a. is that correct

  • math -

    Increase in v: 3 1 3
    Increase in f: 9 3 9

    Looks like f increases to f+3 3 for every v+1

    So, f = 3v+c

    Since f is exactly 3*v, c=0, and

    f(v) = 3v
