Answer:

3rd option

Explanation:

For it to be a function, it would need to pass the vertical line test where for one x value, there can't be 2 y outputs

The first choice is incorrect because when x = 10, y = 5 or 15

The second choice is incorrect because when x = 2, y = 6 or 7

The fourth choice is incorrect because when x = 20, y = 25 or 15
