Define max(f,g) and min(f,g) as max(f,g)(x) = max {f(x),g(x)} and min(f,g)(x) = min {f(x),g(x)}. Show that max(f,g)=(1/2)*(f+g)+(1/2)*|f-g| and min(f,g)=(1/2)*(f+g)-(1/2)*|f-g|. (You can show this by first showing that for all m,n belonging to R, max{m,n}=(1/2)*(m+n)+(1/2)*|m-n|. Do this by considering the two cases m>=n and m
