LIMITS OF A FUNCTION
A function f(x) is said to approach a value A as x
approaches a, if corresponding to every positive number
Є there is some positive number such that
is true for every x that satisfies the inequality
CONTINUITY AND DISCONTINUITY
A single-valued function f(x) is said to be
continuous at a value a of its domain
provided that:
A function that is not continuous at a point is
said to be discontinuous at that point.
