There is another way we can write interval notation. It is called set-builder notation. Set builder notation is the descriptive definition of the set.
- x < 4 Interval Notation: (-∞, 4) Set Builder Notation: {x| x is a real number less than 4}
- 3 < x < 8 Interval Notation: (3, 8] Set Builder Notation: {x| x is a real number greater than 3 and less than or equal to 8}
- x > 100 Interval Notation: [100, ∞) Set Builder Notation: {x | x is a real number greater than or equal to 100}
