Question

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

Answer 1

A is the correct answer.

By definition, a function is a relation where each input has exactly one output. In letter A, the inputs 0, 1, 2, and 3 all have exactly one output.

In B, the input 1 has two outputs.

In C, the input 2 has two outputs.

In D, the input 2 also has two outputs.
