If a function is continuous at every point in an interval [a, b], we say the function is “continuous on [a, b] .” WebA function is continuous if it is continuous at every point of its domain (that is the adopted definition in, say, real analysis). Going with the definition of continuity of a function f: D → R at a point x 0 is a starting point : ∀ ε > 0, ∃ δ > 0 s. t. ∀ x ∈ D, x − x 0 < δ ⇒ f ( x) − f ( x 0) < ε
