1. which relation is a function? (0, 4), (-4, 2), (7, 1), (-8, 2) (0, 4), (-4, 6), (0, 3), (-8, 2) (0, 0), (-4, 3), (7, 1), (-4, 5) (7, 1), (-4, 4), (0, 1), (7, 2) 2. which relation is a function? (2, 0), (-3, 3), (9, 1), (-3, 5) (9, 1), (-3, 4), (2, 1), (9, 2) (2, 4), (-3, 2), (9, 1), (-7, 2) (2, 4), (-3, 6), (2, 3), (-7, 2)

1. (0, 4), (-4, 2), (7, 1), (-8, 2)

2. (2, 4), (-3, 2), (9, 1), (-7, 2)

Step-by-step explanation:

1. Since there is 1 value of y for every value of x in (0, 4), (-4, 2), (7, 1), (-8, 2) this relation is a function.

2. Since there is 1 value of y for every value of x in (2, 4), (-3, 2), (9, 1), (-7, 2) this relation is a function.
