Closed Interval Definition
A closed interval is the interval which contains the end points. It is represented by square brackets. An example of closed interval is [a, b] where a and b are included.
Closed Interval Example
An example of closed interval is numbers greater than or equal to -2 and less than or equal to 3 i.e., closed interval [-2, 3]. The closed interval [-2, 3] includes the numbers from -2 to 3 where -2 and 3 are included.
Closed Interval in Number Line Representation
The closed interval in the number line is represented by a filled circle. Below number line shows the closed interval representation in number line.
Open Interval and Closed Interval
A closed interval includes its endpoints and is enclosed under square brackets. An open interval does not include its endpoints and is enclosed under parenthesis. In this article, we will explore the difference between an open interval and a closed interval, along with the open interval and closed interval definitions. Let’s start our learning on the topic “Difference Between an Open Interval and a Closed Interval”.
