The Intermediate Value Theorem is found in Section 2.5 together with an application, using a binary search to approximate a zero of a function. 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 arent supposed to be (along the \(x\)s).
