Definition

Let be a function defined on a subset of real numbers. can be , or any closed or open interval.

Definition in terms of limits of functions

is continuous in if:

Definition in terms of neighborhoods

is continuous in if:

for any neighborhood there is a neighborhood in its domain such that whenever .

Generalization in metric spaces

Continuity can be generalized for metric spaces, see continuous mapping.
