Question

The range of the following relation R {(3, −5), (1, 2), (−1, −4), (−1, 2)} is

Answer 1

bearing in mind the domain is always the x-values from the pairs and the range is the y-values from the pairs.


`\bf R~\{(3, \stackrel{\downarrow }{-5}), (1, \stackrel{\downarrow }{2}), (-1, \stackrel{\downarrow }{-4}), (-1, \stackrel{\downarrow }{2})\}\qquad \qquad \stackrel{Range}{-5,2,-4}`
