Which set of ordered pairs represents a function?
1) {(0,4),(2,4),(2,5)}
2) {(6,0),(5,0),(4,0)}
3) {(4,1),(6,2), (6,3),(5,0)}
4) {(0,4),(1,4),(0,5),(1,5)}
Option 1

Answer 1

2

Explanation:

This is the only set of ordered pairs that represents a function because if this function was graphed, it would pass the vertical line test. Looking at the ordered pairs, a function must not have more than one ordered pair that has the same x-coordinate values. All the other answer choices have 2 or more ordered pairs with the same x-values, meaning 2 is the correct answer.
