Web1: If A and B are in same x, then f ( x) = A and g ( x) = B. Then, we have that ( f + g) ( t) = A + B. Hence, sup ( f + g) = sup ( f) + sup ( g). 2: If A and B are not in same x, then f ( p) = A and g ( q) =. Hence, sup ( f + g) ≤ A + B. From 1 and 2, we have that. sup ( f + g) ≤ sup ( f) + sup (.
