Piecewise Functions
Overview
Goal. Evaluate piecewise functions by matching the input to its condition, settle boundary inputs correctly, and read piecewise graphs with open and closed circles.
Piecewise function (definition). A function defined by different rules (pieces), each rule applying to a different part of the domain.
