This is a free lesson from our course in Algebra I

 In this lesson you'll learn how to determine the range and domain of a function from a finite set of ordered pairs. In a finite set of ordered pairs, the domain is a finite set of x values and the range is a finite set of y values. For example, Consider the ordered pairs {(1, 2), (2, 4), (3, 1), (4, 9)}, here 2, 4, 1, and 9 are the images of the elements 1, 2, 3, and 4. So domain is the x values {1, 2, 3, 4} and range is the y values {2, 4, 1, 9}.
