Lecture 9: Continuity (Sections 2.4 and 2.8) Def. Aunin f is continuous at a number c if x→c f(x)= If f is deﬁned on an open interval including x = c but is not continuous there, then f is discontinuous at c. The deﬁnition implies three conditions for continuity: 1. 2. 3. Note that f is continuous at x = c if the limit as x → c gives the same number as evaluating the function at x = c.
