In speaking one might say a function approaches a certain value as x increases, decreases, or approaches a certain value. To mathematically say "approaches an arrow is used. For example, to say that the function f ( x ) increases without bound as x increases without bound, one would write f ( x )Ü as x Ü.
Or to say the function f decreases without bound as x approaches 0, you would write f ( x )Ü - as x Ü 0. Rational functions often have what are called asymptotes.
