Expressing inequalities in interval notation
How do you write an interval notation?
In "Interval Notation" we just write the beginning and ending numbers of the interval, and use: [ ] a square bracket when we want to include the end value, or. ( ) a round bracket when we don't.
How to write the solution in interval notation?
In interval notation, you write this solution as (-2, 3]. The bottom line: Both of these inequalities have to be true at the same time. You can also graph or statements (also known as disjoint sets because the solutions don't overlap). Or statements are two different inequalities where one or the other is true.
Which number is the solution for the inequality?
A solution to an inequality is a number that can be used in place of the variable to make the inequality true. For example, 5 is a solution to the inequality c < 10, because it is true that 5 < 10. Some other solutions to this inequality are 9.9, 0, and -4. Lesson 9 Practice Problems
Which numbers are solutions of the inequality?
Like systems of equations, system of inequalities can have zero, one, or infinite solutions. If the set of solutions includes any shaded area, then there are indeed an infinite number of solutions. (5 votes) See 2 more replies

4 <x<5, then in interval notation we would write ( 4;5), which looks like and may be easily confused with the point with x-coordinate -4 and y-coordinate 5. It is therefore important, in order to avoid confusion, to use the word interval in conjunction with in-terval notation. We would say the interval ( 4;5) is the set of all numbers xthat satisfy

We won’t even know if we have an “and” or an “or” situation until we isolate the absolute

INTERVAL NOTATION (SECTION 1.1) A set is a collection of objects whose contents can be clearly determined. The objects in the set are called the elements of the set. Sets of real numbers can be represented using one of the following forms: 1. SET – BUILDER NOTATION. In this notation the elements are described, but not listed.

As a prompt, ask students how they would draw and and how these might be combined. The correct answer is: Students should now feel confident in expressing an interval in inequality notation and using number line diagrams. Aspects of this topic will be considered in Developing Understanding 2, which considers set notation.
