PIECEWISE

Piecewise

In mathematics, a piecewise-defined function is a function which is defined by multiple subfunctions, each subfunction applying to a certain interval of the main function's domain . Piecewise is actually a way of expressing the function, rather than a characteristic of the function itself, but with additional qualification, it can describe the nature of the function. For example, a piecewise polynomial function: a function that is a polynomial on each of its subdomains, but possibly a different one on each.
