(a) Let f, 9, h : N → R²º. Prove or disprove that if f + g€ O(h), then f e O(h) and gE O(h). (b) For all functions f, g : N→ R2º, define the product function f · g : N → R2° as follows: Vn E N, (f - g)(n) = f(n) · g(n). Let f, g,h : N → R²º. Prove or disprove that if f ·g€ O(h), then ƒ € O(h) and E O(h).

(a) Let f, 9, h : N → R²º. Prove or disprove that if f + g E O(h), then f E O(h) and ge O(h). (b) For all functions f, g : N → Rº, define the product function f·g:N → R20 as follows: Vn e N, (f · g)(n) = f(n) · g(n). Let f, 9, h : N → R²°. Prove or disprove that if f ·g€ O(h), then f E O(h) and g E O(h).
