As the values of x approach 2 from either side of 2, the values of y = f(x) approach 4. Mathematically, we say that the limit of f(x) as x approaches 2 is 4.

WebIf all values of the function f(x) approach the real number L as the values of x( ≠ a) approach the number a, then we say that the limit of f(x) as x approaches a is L. (More succinct, as x gets closer to a, f(x) gets closer and stays close to L .) Symbolically, we express this idea as lim x → af(x) = L.
