Do the set of ordered pairs {(2,6),(-3,6),(4,9),(2,10)} represent a function?

x | y | Occurrences of x |
---|---|---|

2 | 6 | 1 |

-3 | 6 | 1 |

4 | 9 | 1 |

2 | 10 | 2 |

Because the x values of 2 occur more than once, the set of ordered pairs you entered are

The Domain is just the input values

Domain = (2, -3, 4)

The Range is just the input values

Range = (6, 9, 10)
