LIMIT of FUNCTION

1. DEFINITION of the LIMIT of a FUNCTION

l Limit of a function is one of the fundamental concepts in calculus and analysis, about the behavior of a function near a particular input point.

l If f :R"R defined on the real number line, and p, L "R then we call f the limit as x approaches p is L, written as:
