The function f is said to be continuous at the number â€˜aâ€™ if and only if the following three conditions are satisfied: f (a) exists; lim xâ†’a f (x) exists; lim -xâ†’a f (x) = lim +xâ†’a f (x) =

A function is discontinuous at a point x = a if the A function being continuous at a point means that the two-sided limit at that point exists and is equal to the function's value.
