The relation would not be a function with which additional ordered pair? { (5.0), (6.4), (7.6), (9.4)} Answers: (5.5) (2.6) (4.9) or (8.1)
Help please! :)
Ok so if you have two or more points with the x's being same but the y's being different then the relation is not a function
yes.. @myininaya just wrote what i wanted. a function has a unique image in y for every x in its domain.
