    There is some debate about when the concept of functions was developed, but most scholars use it as a distinguishing feature of “modern” mathematics. Scholar W. L. Schaaf goes even further, saying that: “The keynote of Western culture is the function concept, a notion not even remotely hinted at by any earlier culture.” (1) Students can thus understand the need to learn how to find functions and how to use functions machines not only as a practical necessity but also as a means of celebrating Western culture and modern mathematics.
