Piecewise Function

Pronunciation: /ˈpisˌwaɪz ˈfʌŋk.ʃən/ Explain
Graph of the function f of x equals x square if x is less than zero, equals x if x is greater than or equal to zero.

A piecewise function is a function that consists of multiple sub-functions, each applying to a different domain. An example of a piecewise function is The function f of x equals x square if x is less than zero, equals x if x is greater than or equal to zero..

In the piecewise function The function f of x equals x square if x is less than zero, equals x if x is greater than or equal to zero., there are two domains: x<0 and x≥0. When x<0, the value of the function is x2. When x≥0, the value of the function is x.
