How to write interval notation.

Answer: Interval notation: [ − 1, 3) Alternatively, we may interpret − 1 ≤ x < 3 as all possible values for x between or bounded by − 1 and 3 on a number line. For example, one such solution is x = 1. Notice that 1 is between − 1 and 3 on a number line, or that − 1 < 1 < 3.

Intervals of Increasing/Decreasing/Constant: Interval notation is a popular notation for stating which sections of a graph are increasing, decreasing or constant. Interval notation utilizes portions of the function's domain (x-intervals). For the graph shown above, we would write: The function is increasing on the x-intervals (-5,-2) and (1,3).Here are a few sample questions going over interval notation.
