1. Your choice of A does not produce the corre2 ct value of y for a single n.
Are you just guessing so that somebody will give you the right answer?

Now, place the given values of n , that is: n= 3, 4, 5, 6 into each of the given
functions and see if they produce y = 2, 1, 0, -1 respectively
e.g. in A.
if n = 1, y = 2 + 1 = 3, but we are to get 2, so A. is Wrong!
etc

4. If for C. you got the correct values of y foe the given n, then you should be 100% certain that it is.
