Continuity and Limits. Continuity. Continuity can be defined conceptually in a few different ways. A function is continuous, for example, if its graph can be traced with a pen without lifting the pen from the page. A function is continuous if its graph is an unbroken curve; that is, the graph has no holes, gaps, or breaks. But terms like unbroken curve and gaps aren't technical mathematical terms and at best, only provide a reader with a description of continuity, not a definition.
