Learn how to graph piecewise functions. A piecewise function is a function which have more than one sub-functions for different sub-intervals(sub-domains) of the function’s domain. To graph a piecewice function, we graph the different sub-functions for the different sub-intervals of the function’s domain. #functions #piecewisefunctions
