Usually, this is used to describe a certain span or group of spans of numbers along a axis, such as an x-axis. However, this notation can be used to describe any group of numbers. For example, consider the set of numbers that are all greater than 5.

If two or more intervals are interrupted with a gap in the number line, set notation is used to stitch the intervals together, symbolically. The symbol we use to combine intervals is the union symbol: ∪. The table below shows four examples: Interval Notation. Graph.

For example, if the domain includes all real numbers greater than 0, you can represent it as (0, ∞), and if the range includes all non-negative real numbers, it can be expressed as [0, ∞). The first interval must indicate all real numbers less than or equal to 1. So, this interval begins at \displaystyle -\infty −∞ and ends at \displaystyle -1 −1, which is written as …

Set notation and interval notation are ways to represent a range of values within certain limitations. So we're going to talk about the format for writing within each notation. And then we'll do some examples. So let's start by talking about set notation. I've got a graphical representation of a set of numbers. And I'm going to show you how you ...Read aloud, this would be "x is less than or equal to 0". The shaded region then represents every number that is less than, or smaller than, 0. It also includes 0, shown with the shaded dot. Note: > is greater than. ≥ is greater than or equal to. < is less than. ≤ is less than or equal to. Refer to the following table for help with …Definition. domain. The domain of a function is the set of x-values for which the function is defined. Interval Notation. Interval notation is the notation [a,b), where a function is defined between a and b.
