Answer:
See in Explanation
Explanation:
All you know is that an 
algorithm is eventually (a lot) faster than an 
algorithm, but for any specific value of n, you can't say anything. Indeed, the asymptotic growth of the function doesn't depend on its value on 
. This means that if 
then for all 
, the following function is also :
So asymptotic notation is completely uninformative regarding the performance of algorithms on specific values of n.
You could say that functions such as 
are artificial and never really occur in practice. This is not quite true (you can hard-code some auxiliary information for small n, for example), but even if you consider "natural" functions, asymptotic notation doesn't help you to determine anything other than asymptotic's: consider for example 
against 
(such examples definitely happen in practice, for example in fast matrix multiplication).
I believe the correct answer would be letter. The default size of paper for documents would be letter. It has dimensions of 8.5 inches x 11 inches. You can see this clearly when you open a blank word file. However, you can freely change this.
The answer is the second one.
Hope this helps! :)
