This is a teacher resource for functions consisting of a website and a PDF with identical content. It contains a review of interval and set notation, an introduction to function notation and domains and ranges, and a discussion of finding the implicit or maximal domain of a function. The Links forward section considers functions other than those defined on the real numbers or a subset of the real numbers. The resource is important for an understanding of calculus. A brief history of functions is presented.
