I have a couple of questions asking me to evaluate limits at infinity, but I am a bit confused.

These are the questions given in the example:

Question: Evaluate limx->infinity (1) / (x+1)

Question: Evaluate limx->infinity (x^3 + x^2 - 3) / (4x^3)

So I'm not sure what the process is to solve questions like these so that I can use the same process in my homework questions.

Any help is appreciated.
