**Find the domain and range. Give answers in ascending order. Example: {-2, 1, 5} but not {1, -2, 5}**

**{** (8, 13), (5, -2), (4, 11), (8, 12) **}** Domain:
Range:
The domain contains all the input values: 8, 5, 4, 8

The range contains all the output values: 13, -2, 11, 12

Remember that duplicate values only need to be listed once.

The answer is Domain:
Range:

**Find the domain and range. For ∞, use "inf". Example: Use (-inf, inf) for (-∞, ∞)
**

For the union symbol ∪, use capital "U".
Expressions under radicals must be greater or equal to 0.

To find the domain, solve x - 1 ≥ 0:

x - 1 | ≥ | 0 |

x - 1 + 1 | ≥ | 0 + 1 |

x | ≥ | 1 |

To find the range, square roots must be greater or equal to 0. Therefore, f(x) ≥ 0.

The answer is Domain:
Range:
