Question

_Don't Understand_

Answer 1

F(n) = y and n = x

just a matter of subbing...I will be subbing 6 in for y and 2 in for x
A. f(n) = n + 3
    y = x + 3
    6 = 2 + 3
   6 = 5 (nope...so its not A)

B. f(n) = 1/3n
     y = 1/3x
     6 = 1/3(2)
     6 = 2/3 (nope....not this one either)

C. f(n) = 3n
      y = 3x
      6 = 3(2)
      6 = 6 (got it.....its this one)

Answer 2

Answer:

C. f(n) = 3n

     y = 3x

     6 = 3(2)

     6 = 6 (got it.....its this one)
