Prove (using the formal definitions of asymptotic notations) or disprove (by counterexample) each of the following claims: (a) f(n) − g(n) = O(s(n) − r(n)) (b) if s(n) = O(g(n)), then f(n) = O(r(n)) (c) if r(n) = O(s(n)), then g(n) = O(f(n)) (d) if s(n) + g(n) = O(f(n)), then f(n) = Θ(s(n))

Prove that if f (n) = O (g (n)) and g (n) = Ohm (h (n)), it is not necessarily true that f(n) = O (h (n)). You may assume that low degree (i.e., low-exponent) polynomials do not dominate higher degree polynomials, while higher degree polynomials dominate lower ones. For example, n^3 notequalto O (n^2), but n^2 = O (n^3). Prove that if f (n) = O (g (n)) and g (n) = Ohm (h (n)), it is not necessarily...
