Question
This problem has two parts but I can only see this so far. I probably over thinking..what is this asking for? How do I answer it?
To evaluate
lim x→ infinity sqrt(x^2 + 4)
*first consider that as x becomes infinitely large
x^2+4 -> __?__

would this just be infinity that they are looking for?

that's correct.
as x gets huge, the 4 is insignificant, so you just have sqrt(x^2) = x.
