Is the relation a function? State the domain and range.
a. {(14, 15), (5, 7), (3, 10), (11, 1), (5, 8)}
b. {(1, 2), (3, 2), (6, 2), (10, 2), (25, 2)}
a. No, the relation is not a function because the input value 5 corresponds to two different output values (7 and 8).
Domain: {14, 5, 3, 11}
Range: {15, 7, 10, 1, 8}
b. Yes, the relation is a function because each input value corresponds to the same output value (2).
Domain: {1, 3, 6, 10, 25}
Range: {2}
