If 3 is a zero of the polynomial f(x), then which of the following is NOT necessarily true?
A. (x – 3) is a factor of the polynomial f(x).
B. 3 is a solution of the equation f(x) = 0.
C. (3, 0) is an xintercept for f.
D. (0, 3) is a yintercept for f.

D.
x=0, y = 3 is NOT necessarily true. All you know for sure is that y = 0 when x = 3.
