I'm not understanding this question.

Which of the following time complexities is approximately of order O(nlogn)

A) 300n + 400n*n

B) n*n*n + nlogn

C) 23nlogn + 50

D) 45logn + 503

Sooo... I think that its "C) 23nlogn+50" because big-Oh notation allows us to ignore constant factors and lower order terms and focus on the main components of a function that affect its growth????
