Cannot be determined Yes No Is this a function? Yes No Cannot be determined Is this a function? Cannot be determined Yes No Cannot be determined Yes No Is this a function? Function? Yes No Cannot be determined No Cannot be determined Yes Is this a function? What is the domain of the following relation? {(4, 1), (-3, 1), (3, 6)} {1, 6} {-3, 3, 4} {4, 3} {-3, 1, 3, 4, 6} What is the range of the relation? {(-1, 4), (2, 4), (6, -4), (0, 3), (5, 3)} {-1, 0, 2, 5, 6} {-4, 3, 3, 4, 4} {-4, 3, 4} {4, 3} When determining whether a relation is a function, which coordinate cannot repeat? x-coordinate y-coordinate x- and y-coordinates Which coordinate is the domain? x-coordinate y-coordinate z-coordinate the domain does not consist of any coordinates Remember: a relation is a set of ordered pairs. Is this relation a function? {(1, 4), (-5, 2), (4, 1), (1, 6)} Yes No, because "1" repeats No, beause "4" repeats Cannot be determined |
