The big-O notation for f(n) = (nlogn + n^2)(n^3 + 2) is?(a) O(n^2)(b)

1.	The big-O notation for f(n) = (nlogn + n^2)(n^3 + 2) is?(a) O(n^2)(b) O(3^n)(c) O(n^4)(d) O(n^5)This question was posed to me by my school teacher while I was bunking the class.This key question is from The Growth of Functions in section Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Correct OPTION is (d) O(n^5) The EXPLANATION: 0 < n^3 + 2 < n^3, it follows that (nlogn + n^2)(n^3 + 2) is less than equal to n^5.
