f(x)=f(2x)=3. Is it strictly a constant function?? 1. The problem statement, all variables and given/known data f(x)=f(2x)=3. can we say that it is constant. Nothing else.. 2. Relevant equations BRAIN>>>> 3. The attempt at a solution f(1)=f(1/2)=f(1/4)=f(1/8).........f(1/∞)=f(0)=3 I think no there can be many functions having such property and constant function is one of them. AM i correct..?
