How do you show a function is continuous

WebHow can you tell if a function is continuous? We can define continuous using Limits . A function f is continuous when, for every value c in its Domain: f (c) is defined, and: "the limit of f (x) as x approaches c equals f (c)" The limit says: "as x gets closer and closer to c then f (x) gets closer and closer to f (c)" WebWe can use the following condition to check whether a function is continuous or not. A function f (x) continuous at a point x = a, if f (a) exists, lim x→a f (x) = f (a) and lim x→ a- f (x) = lim x→ a+ f (x) = f (a). (LHL = RHL). List two properties of Continuous Functions.
