Concept (1)

When we evaluate limits of a function as (x) goes to infinity or minus infinity, we are examining something called the end behavior of a limit. In order to determine the end behavior, we need to substitute a series of values or simply the function determine what number the function approaches as the range of the function increases or decreases towards infinity or minus infinity.
