All of the following are rules to determine Big-Oh notation for a function EXCEPT:
Group of answer choices
nlogn
You can ignore constant factors. 5n2 is just O(n2)
If you have more than one of the Seven Basic Functions, only use the fastest growing. For instance, 5n4+3n3+2n2 is O(n4).
If more than one function provide an asymptotic bound, either would be correct, but use the one with the tightest bound. 3x is both O(x) and O(x2), but it's better to say O(x).
