There are several ways to define sets of numbers or mathematical objects. The reason we are introducing this here is because we often need to define the sets of numbers that make up the inputs and outputs of a function. How we write sets that make up the domain and range of functions often depends on how the relation or function are defined or presented to us. For example, we can use lists to describe the domain of functions that are given as sets of ordered pairs. If we are given an equation or graph, we might use inequalities or intervals to describe domain and range. In this section, we will introduce the standard notation used to define sets, and give you a chance to practice writing sets in three ways, inequality notation, set-builder notation, and interval notation. It is the set of all elements that belong to one or the other or both of the original two sets.

Each of the students in the problem above used correct notation! However, Mrs. Glosser told them that there was another way to write this set:. Let's look at some more examples. Both the colon and the vertical line represent the words "such that". Let's look at these examples again.

Write each set of numbers in set-builder and interval notation, if possible

The set of all even integers , expressed in set-builder notation. In set theory and its applications to logic , mathematics , and computer science , set-builder notation is a mathematical notation for describing a set by enumerating its elements , or stating the properties that its members must satisfy. Defining sets by properties is also known as set comprehension , set abstraction or as defining a set's intension. A set can be described directly by enumerating all of its elements between curly brackets, as in the following two examples:. This is sometimes called the "roster method" for specifying a set. When it is desired to denote a set that contains elements from a regular sequence, an ellipses notation may be employed, as shown in the next examples:. There is no order among the elements of a set this explains and validates the equality of the last example , but with the ellipses notation, we use an ordered sequence before or after the ellipsis as a convenient notational vehicle for explaining which elements are in a set.

I use it to access their prior knowledge of inequalities or refresh their memory if necessary. Having a clear understanding of what the inequalities symbols mean, will help my students to achieve the goal of this lesson: to write the domain and range of a graph using set builder notation. I have students use two colored pencils for this activity. One color for domain and one color for range. Most of the students know that domain is what possible x's and the range is what possible y's.

Наделенный феноменальной памятью и способностями к языкам, он знал шесть азиатских языков, а также прекрасно владел испанским, французским и итальянским. На его лекциях по этимологии яблоку негде было упасть, и он всегда надолго задерживался в аудитории, отвечая на нескончаемые вопросы. Он говорил авторитетно и увлеченно, не обращая внимания на восторженные взгляды студенток.

Все глобальное электронное сообщество было обведено вокруг пальца… или так только. ГЛАВА 5 Куда все подевались? - думала Сьюзан, идя по пустому помещению шифровалки.

Последний из трех миллионов процессоров размером с почтовую марку занял свое место, все программное обеспечение было установлено, и керамическая оболочка наглухо заделана. ТРАНСТЕКСТ появился на свет. Хотя создававшийся в обстановке повышенной секретности ТРАНСТЕКСТ стал плодом усилий многих умов и принцип его работы не был доступен ни одному человеку в отдельности, он, в сущности, был довольно прост: множество рук делают груз легким. Три миллиона процессоров работали параллельно - считая с неимоверной скоростью, перебирая все мыслимые комбинации символов. Надежда возлагалась на то, что шифры даже с самыми длинными ключами не устоят перед исключительной настойчивостью ТРАНСТЕКСТА.

Она молила Бога, чтобы Стратмору звонил Дэвид. Скажи мне скорей, что с ним все в порядке, - думала.  - Скажи, что он нашел кольцо. Но коммандер поймал ее взгляд и нахмурился. Значит, это не Дэвид.
