How to find the domain and range of piecewise functions - In its simplest form the domain is all. If we input 0, or a positive value, the output is the same as the input.į\left(x\right)=x\textx $10,000. A piecewise function is a function in which more than one formula is used to define the output over different pieces of the domain. How to find the domain and range of piecewise functions. All of these definitions require the output to be greater than or equal to 0. It is the distance from 0 on the number line. With a domain of all real numbers and a range of values greater than or equal to 0, absolute value can be defined as the magnitude, or modulus, of a real number value regardless of sign. For example, in the toolkit functions, we introduced the absolute value function f\left(x\right)=|x|. The range of a piecewise function is the set of all output values for which the function produces a result. Sometimes, we come across a function that requires more than one formula in order to obtain the given output. A piecewise defined function is actually a collection of two or more functions that tell us how to use an input to get an output.
