A relation is a set of ordered pairs is called a relation while a function is a relation that has some specific properties. We use mapping to visualize the relations and easily determine if the relation is a function or not, or if the function is a one-to-one or not. The coordinate plane describes each point as an ordered pair (x,y). The first element is the x-coordinate and the second is the y-coordinate. And the coordinate plane is divided into four quadrants. In this lecture, youll learn about domain, range, how to represent and graph a relation, and how to determine a function from a graph.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
