please answer parts

ii) , iii) , v) , vi)

thank you

For each of the following pairs of functions, either f(n) is O(g(n)), f(n) is S2(g(n)), or f(n) is (g(n)). For each pair, determine which relationship is correct. Justify your answer. f(n) = log n; g(n)= vn log n. i) f(n) = nyn + logn; g(n)-log n. ii) f(n) = 2n; g(n) = log n. iii) f(n)= vn; g(n) = 2Vlogn v) f(n) = 20; g(n)=n". vi) f(n) = 50; g(n) = log 60
