Any numbers which lies between any two given real numbers is an interval in math and also the set of all real numbers. For example an interval 5 $\leq$ x $\leq$ 9 contains all elements which are lies from 5 to 9. Interval is in set of all positive and negative real numbers. There are different types of interval they are open interval, closed interval, half open interval and half closed interval.
Interval Notation is defined as representing the given numbers in terms of symbols like brackets ( ), square brackets [ ], less than or greater than symbol < >, infinity $\infty$, and union sign $\cup$. The interval notation is used to represent the range of values of the given problems. Here ( ) this symbol represents open interval while [ ] symbol represents closed interval.
We can express the inequality outcomes by solving the interval notation
The symbols used in solving the interval notation are:( $\Rightarrow$ is the “not included” symbol or “open” symbol
[ $\Rightarrow$ is the “included” symbol or “closed” symbol
Interval Notation Calculator (set builder notation calculator) is used to find the inequality and graph on a number line for the given interval. It is a interval notation solver that represent the interval as per the interval given. It is sometimes called interval notation calculator online or domain calculator interval notation or interval notation converter. You just have to enter the interval and get it represented on graph instantly.
You can see a default interval given below. The calculator first observes the interval and write the inequality and then number line is drawn when you click on "Calculate".
