Answer:
{(-3, -3), (-2, -2), (-1, -1), (0, 0), (1, 1)}.
Explanation:
The set of ordered pairs representing a function is the set A) {(-3, -3), (-2, -2), (-1, -1), (0, 0), (1, 1)}. In a function, each value of x has only one corresponding value of y. In the set A), each value of x has a single associated value of y, which fulfils the definition of a function. In the other sets (B, C, D), there are repeated values of x with different values of y, which does not meet the definition of a function.
