![]() If we input 0, or a positive value, the output is the same as the input.į\left(x\right)=x\textx $10,000. 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. If your problem is a complete algebraic expression involving equality or inequality signs then select for equation or. For example, in the toolkit functions, we introduced the absolute value function f\left(x\right)=|x|. Note that there is an example of a piecewise function’s inverse here in the Inverses of Functions section.Sometimes, we come across a function that requires more than one formula in order to obtain the given output. ![]() Thus, the \(y\)’s are defined differently, depending on the intervals where the \(x\)’s are. The easiest way to think of them is if you drew more than one function on a graph, and you just erased parts of the functions where they aren’t supposed to be (along the \(x\)’s). Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph.

Each piece behaves differently based on the input function for that interval.
