Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph. 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 ’s); they are defined differently for different intervals of . So is defined differently for different values of ; we use the to look up what interval it’s in, so we can find out what the is supposed to be. Note that there is an e…
