WebJan 20, 2024 · Big O Notation (Represented as O) Let f (n) f (n) and g (n) g(n) be two functions dependent on the input variable n. So, the function f (n) = O (g (n)) f (n) = O(g(n)) if there exists some positive constants c c and n' n′ such that f (n) <= c.g (n) for all n >= n' n >= n′. For example, let f (n) = 2n + 5. WebProof: by the Big-Omega definition, T(n) is Ω(n2) if T(n) ≥ c·n2 for some n ≥ n0 . Let us check this condition: if n3 + 20n ≥ c·n2 then c n n + ≥ 20. The left side of this inequality has the minimum value of 8.94 for n = 20 ≅4.47 Therefore, the Big-Omega condition holds for n ≥ n0 = 5 and c ≤ 9.
