I have a HW problem that asks in two parts to prove i) that if an additive function is continuous at 0 then it is continuous in R, and ii) if a subadditive function is continuous at 0 and f(0)=0 then the subadditive function is on R. I did the first part but dont know how to do the second. Any help would be great.(adsbygoogle = window.adsbygoogle || []).push({});
