Continuous Functions - Concept

Concept Concept (1)

In order for a function to have continuity at a certain point, several conditions including (1) the existence of the point in the domain and (2) the existence of a two-sided limit as the point approaches the limit must be met. If functions are continuous at every point in their domain, they we call these functions continuous functions. Examples of continuous functions are power functions, exponential functions and logarithmic functions.
