Interval notation is a notation used to denote all of the numbers between a given set of numbers (an interval). For example, "all of the integers between 12 and 16 including 12 and 16" would include the numbers 12, 13, 14, 15, and 16.

2024年6月10日 · Interval notation is a method used in mathematics to describe a range of real numbers between two endpoints on a number line. It uses brackets and parentheses to indicate whether the endpoints are included or excluded from the interval.

Interval notation is a way to represent a set of real numbers on the number line. It consists of two numbers separated by a comma, and the numbers are enclosed in either parentheses or square brackets.

Interval notation We use interval notation to represent subsets of real numbers. Suppose that a and b are real numbers such that a < b. Then, the open interval (a,b) represents the set of all real numbers between a and b, except a and b. { x / a < x < b} is the set-builder notation. a < x < b is the inequality description.

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 better using solved examples.

A few examples of an interval, or a set of numbers in which a solution falls, are [− 2, 6), or all numbers between − 2 and 6, including − 2, but not including 6; (− 1, 0), all real numbers between, but not including − 1 and 0; and (− ∞, 1], all real numbers less than and including 1.
