Are Sets of Ordered Pairs Functions?
Example 3:
Is the relation {(5, -3), (-3, 5), (-3, 6), (-4, 6)} a function? Explain your answer. Then find the domain and range.
No, the relation {(5, -3), (-3, 5), (-3, 6), (-4, 6)} is not a function because the input value -3 is associated with two different output values, 5 and 6.
Domain: {5, -3, -4}
Range: {-3, 5, 6}
