In mathematics, a function can be defined as a rule that relates every element in one set, called the domain, to exactly one element in another set, called the range. For example, y = x + 3 …

Let’s go over a few more examples by identifying if a given relation is a function or not. Example 1: Is the relation expressed in the mapping diagram a function? Each element of the domain is …

This section covers an introduction to both relations and function. The concept of domain and range are covered, and many examples are presented in visual, graphical and mathematical …
