The Attempt at a Solution


First, i manipulated the given function to take out absolute (x) from the square root



so, what i get is, limit absolute value (x) square root (1+1/x) +x



now, i get infinity - infinity. (looks like an indeterminate form)

I do not know where to go from this point.



Thanks

Pull the x down into the denominator, then use L'Hopital's rule.
