Identify the domain and range of each relation. Use a mapping diagram to determine whether the relation is a function.
1. {(-2, 5), (8, 6), (3, 12), (5, 6)}
Domain: _ use brackets in your answer
Range: _ use brackets
Is it a function (Y/N): _
2. {(9, 6), (3, 8), (4, 9.5), (9, 2)}
Domain: _ use brackets
Range: _ use brackets
Is it function (Y/N):_
1. Domain: {-2, 8, 3, 5}
Range: {5, 6, 12}
Is it a function: Yes
2. Domain: {9, 3, 4}
Range: {6, 8, 9.5, 2}
