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. For each region or interval, the function may have a different equation or rule that describes it. Obtaining Equations from Piecewise Function Graphs A piecewise function is a function that is defined in separate 'pieces' or intervals.
