Functions with interesting properties.

Revision en2, by coder_in_use, 2018-11-11 21:46:45

I'm trying to find the function with some properties:
1. f(u) = 0 iff v = 0
2. f(av) = |a| f(v)
Does these kind of functions exist and if yes, how do they called and where can I get more info about it?

Thanks in advance!
