Have you ever wondered why an inequality with an "equal to" has a closed dot rather than a open dot ? For example, 2 greater than or equal to would be a closed dot because it can be 2 but it can be greater than to also. One of the reasons of the difference is the meaning. An inequality with a closed dot means greater than or equal to OR less than or equal to.
