is it possible to find a function f different from [tex] f(x)=constant [/tex](adsbygoogle = window.adsbygoogle || []).push({});

with the property [tex] f(kx)=f(x) [/tex] for some real and positive 'k' ???

this is somehow 'dilation periodicity' is the equivalent to the periodic funciton [tex] f(x+k)=f(x) [/tex] for some positive 'k' for the traslation group
