1. (5 pts total, 1 pt each) For each of the following pairs of functions f(n) and g(n), determine only one of f(n) = O(g(n)), f(n) = (g(n)), or f(n) =(g(n)). If f(n) =(g(n)), then do not choose f(n) = O(g(n)) or f(n) = (g(n)).

1. f(n) = 5n⁹, g(n) =(7n⁵ + 5n⁴)/9
2. f(n) = log₆ (n⁷), g(n) = log₇ (n⁶)
3. f(n) = 5ⁿ, g(n) =7ⁿ
4. f(n) = 9 log ₈ n, g(n) = 9 log ₄ n
5. f(n) =7 n³+4n + 3 n², g(n) = 6 n² + 5 n
