piecewise function

A piecewise function is a function defined by multiple sub-functions, each applying to a specific interval of the function’s domain. These sub-functions are defined piece by piece, hence the term “piecewise.” When you observe a graph that is divided into three distinct segments, it suggests that the function’s rule or behavior changes across different intervals or regions of its domain, indicating a piecewise-defined function.
