Which set of ordered pairs represents a function? 1 point A. (-2, 1), (0, 1), (1, -2), (3, 4) B. (-1, 5), (-2, 3), (-2, 1), (-3, -1) C. (12, 36), (9, 27), (-6, 30) (9, 18) D. (3, 17), (-2, 11), (1, 8), (3, 5)

Only A is a function

Step-by-step explanation:

In order to have a function each value of x must pair with exactly ONE value of y

In A, each x pairs with one y, so we have a function

In B, notice that -2 pairs with 3 and 1, so we do not have a function

In C, notice that 9 pairs with 27 and 18, so we do not have a function

In D, notice that 3 pairs with 17 and 5, so we do not have a function

the correct answer to your question is a. 4^4
