### Are the following functions?

Below are sets of ordered pairs. Determine whether each set is a function based on the definition that a function assigns exactly one value to each input.

#### Set 1:
| x | y |
|---|---|
| 7 | 3 |
| 3 | 4 |
| 7 | 3 |
| 3 | 4 |

#### Set 2:
| x | y |
|---|---|
| 1 | 7 |
| 2 | 1 |
| 3 | 4 |
| 2 | 1 |

#### Set 3:
| x | y |
|---|---|
| 7 | 3 |
| 7 | 4 |
| 3 | 2 |
| 1 | 2 |

#### Set 4:
| x | y |
|---|---|
| 7 | 3 |
| 1 | 7 |
| 2 | 7 |
| 4 | 7 |

### Explanation
To determine if each set is a function, verify that every input (x-value) corresponds to exactly one output (y-value). If any input is associated with more than one output, the set is not a function.
