**What is a Set?**

A set is a well defined group of objects or symbols. The objects or symbols are called elements of the set.

**Set-Builder Notation**

A collection of numbers can be described as a set. For example, {1,3,5,9,13} is a set containing the listed numbers.

Set-builder notation can be used to build or describe a set. This is especially helpful if the set has an infinite number of numbers or elements.

Example:

{x:x ≥ -2} or {x|x ≥ -2}

We say, "the set of all x's, such that x is greater than or equal to negative two".

Examples:

1. Graph the interval, then express using inequalities and set-builder notation.

Interval notation: (-∞, 3]

2. Graph the interval, then express using inequalities and set-builder notation.

Inequality: -2 < x ≤ 6

3. Give set-builder notation for each set of numbers.

The set of even numbers. {...-4,-2,0,2,4,...}
