This study guide covers continuity of functions at a point. It defines continuity using a three-part test: f(c) is defined, the limit of f(x) as x approaches c exists, and the limit equals f(c). It explains how to determine continuity from graphs and provides practice questions involving algebraic functions and piecewise functions. The guide also includes multiple-choice and free-response practice problems with solutions and scoring guidelines.
