Finding the limit of a graph is basically finding the point on the graph at which
    there exists no true point. This would be the limit of the graph. It's mostly about
    the points approaching the limit rather than the limit itself. Some of the variables
    involved in this are Epsilon, Delta and Change in (x). Epsilon is the Greek letter
    (E) and Delta is the Greek letter (D).

    In the image above, the components of it are very simple. The Epsilon plus (x) is
    the change in (x), also known as (c). What the image says is this: The function of
    the change in (x) approaches the function of (x) as the change in (x) approaches
    (x). If this is true, then the limit of the change in (x) as Epsilon approaches (?) is
    equal to the function of (x).
