Continuous and differentiable function

Quote Quote by HallsofIvy View Post
Given function f, let [itex]f_e(x)= (f(x)+ f(-x))/2[/itex] and [itex]f_o(x)= (f(x)- f(-x))/2[/itex].
yes f(x)=((f(x)+f(−x))/2 )+(f(x)−f(−x))/2) then (f(x)+f(−x))/2 is even and (f(x)−f(−x))/2 is odd,then i don't know how to argue their continuity and differentiability?
