#Lim_(x->oo)x=oo#

Explanation:

Break the problem down into words: "What happens to a function, #x,# as we continue increasing #x# without bound?"

#x# would also increase without bound, or go to #oo.#

Graphically, this tells us that as we continue heading right on the #x#-axis (increasing values of #x,# going to #oo)# our function, which is just a line in this case, keeps heading upwards (increasing) with no restrictions.
