Hi everyone, try this question:

Suppose that f(1+x)=f(x) for all real x. If f is a polynomial and f(5)=11, then f(15/2) is

(A) -11
(B) 0
(C) 11
(D) 33/2

Answer key:

SPOILER: C

Br,

Obviously it must be the constant function. f(x) = 11 for all x.

Cheers, Md.

You're welcome.

I'm happy to see that I'm not the only one on the forum, who took or is going to take Math subject test.

Cheers, Md.
