Page 1: Is this relation a function? Explain. {(0, 5), (1, 6), (2, 4), (3, 7)} Draw arrows from the domain values to their range values

Is this relation a function? Explain.

 {(0, 5), (1, 6), (2, 4), (3, 7)}

Draw arrows from the domain values to their range values.

Page 2: Is this relation a function? Explain. {(0, 5), (1, 6), (2, 4), (3, 7)} Draw arrows from the domain values to their range values

 {(0, 5), (1, 5), (2, 6), (3, 7)}

Is this relation a function? Explain.

Draw arrows from the domain values to their range values.
