To combine two intervals, use the union sign, In many instances, it is more practical to use interval notation than to list out every number. For example, the interval containing the heights of 1,500 students aged 8 to 14 years may take the value of any real number between 47 and 68...
Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. Understand interval notation bett
We have to write two intervals for this example. The first interval must indicate all real numbers less than or equal to 1. So, this interval begins at−∞−∞and ends at−1−1, which is written as(−∞,−1](−∞,−1]. ...

[a, b] is the interval notation. The table below lists nine types of intervals used to describe subsets of real numbers. Notice the number line representation of each interval.Basically, an interval is a set containing all numbers between two given numbers or endpoints. The set may have one...
Interval Notation Intervals are the subsets of real numbers that contain all the real numbers lying between two real numbers used to define the interval. At times the real numbers that bound such an interval are also included in the subset. Such an interval is called a closed interval. Interva...

R.2 Inequalities and Interval Notation In order to simplify matters we want to define a new type of notation for inequalities. This way we can do away with the more bulky set notation. This new notation is called using intervals. There are two types of intervals on the real number line;...
