Examples of interval notation in math graph
WebHow to Do Interval Notation: Example 1. Graph the interval [−2,5) [ − 2, 5) . Step 1: The equivalent inequality for this interval is the set of x x satisfying −2 ≤ x< 5 − 2 ≤ x < 5. x ... WebNote that on the graph [ and ] are the same as • and ( and ) are the same as . The symbol ∪ represents the union of two or more sets. It is used to combine two (or more) intervals together to make a single set. Example: (−9, −3)∪[2, 5) This means that you have the interval (−9, −3) and the interval [2, 5).
