Question 419538: I have a test this Thursday and I dont understand this review question at all. Can someone please explain to me in detail, step by step, what I should do to solve it? It would really help me alot.
a)Let f(x) and g(x) be real-valued functions of a real variable with domain all large x. Define f(x)=O(g(x)).
b)f(n)= ((3n^5)+2n+20)/sqrt((n^2)+1)

I think you would have gotten a response long before now if we could have understood your question.

For part a, what is "O"

For part b, what are you/we supposed to do with f(n)?
