I am having great, great difficulties in solving this problem, its asking me to find a function that is continuous everywhere which takes each of its values exactly 3 times(like give an example of a function, no proving). This part, i have a little imagination of my own to start, but the second part is the hardest one, which i can't even think about.(adsbygoogle = window.adsbygoogle || []).push({});

It says to prove that there is no such function if there are two values instead of three.
