Let f:R→R be a function such that f(x+1)=f(x) for all x∈R. Which of the
following statement(s) is/are true?
(A) f is bounded.
(B) f is bounded if it is continuous.
(C) f is differentiable if it is continuous.
(D) f is uniformly continuous if it is continuous.
It is a periodic function with period 1. I don't know how to proceed further...
Any Hints will be appreciated...
