Missing something. Functions.
Let f : R > R be a function such that :
f( (x+y) /3) = [f(x) + f(y)] /3 then:
Is f(x) differentiable in R?
Is it continous?
Is f(x)/x differentiable?

Best ResponseYou've already chosen the best response.0How is the function f(x)=kx not differentiable on/in R. Hmm \[\lim_{h \to 0} \frac{3(x+h)  3x}{h}\]

Best ResponseYou've already chosen the best response.0Did you differenciatePut x=0integrate? { To get the function} Or observe? :P That works here too . I got the same thing too. I dunno whats wrong.
