(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

function f:R->R can be written as a sum f=f1+f2 where f1 is even and f2 is odd。show that if f is continuous then f1 and f2 may be chosen continuous, and if f is differentiable then f1 and f2 can be chosen differentiable

2. The attempt at a solution

i have try some examples, but i still cannot get the idea from that
