Use limit value and LHopitals rule to find the relationship of f(n) and g(n) (() = (()), or () = ((), or () = (()). 1) () = (^3 +2)/(2n+1), g(n) = n^2 2) f(n) = (n + 3)^3, g(n) = n^3

Question 2 (20 points) Use limit value and L'Hopital's rule to find the relationship of f(n) and g(n) (f(n)=O(g(n)), or f(n)=(g(n), or f(n)=(g(n)). 1) f(n)=2n+1n3+2n,g(n)=n2 2) f(n)=(n+3)3,g(n)=n3
