Determine whether each relationship represented by the ordered pairs is a function. explain.. answer both problems. 8. (2,2), (3,1), (5,7), (8,0), (9, 9. (0,4), (5,1), (2,8), (6,3), (5,9)

8.) Not a function

9.) Is a function

Step-by-step explanation:

In order for a set of coordinates to be a function, the y cannot be repeated.

In number 8, there is (3,1) and (9,1)

Not a function

In number 9, each coordinate is unique and doesn't repeat the y.

Is a function
