WebSep 30, 2016 · Instead, see if you can start with the initial expression (7n - 2) and massage it into something upper-bounded by cn. Here's one way to do this: since 7n - 2 ≤ 7n, we can (by inspection) just pick n 0 = 0 and c = 7 to see that 7n - 2 ≤ cn for all n ≥ n 0. For a more interesting case, let's try this with 7n + 2: 7n + 2. ≤ 7n + 2n (for ... http://www.cbcie.com/news/710108.html
