I just want to say before my question that I love this forum so so much, I have gotten a lot of help, and you people deserve a noble price for being so smart and helpful and nice.
For my question, I have another question about big-oh-notation, I am finally starting to understand the concept of it better, but I still struggle with some fundamental problems.
So, the problem is:
Show that (x2 + 1) / (x + 1) is O(x)
My book really has no good explanation on how to think when trying to find a constant C and k for which this is true. I thought maybe someone here would know a fancy way to do it?
