Answer:
Yes!, This is a function
Explanation:
A group of ordered pairs with the form (x, y) is a function if every value of x is related to just one value of y.
In this case:
1 is related to 5
3 is related to 7
6 is related to 5
9 is related to 8
Since 1, 3, 6, and 9 are related to one value, we can say that this is a function.
