### Set

2

## Used if the set contains few elements that do not have a common property.

### Roster or List Method

3

## Used if the set has many or an infinite number of elements. Denoted by the symbol "x|x".

###
Universal Set

(Denoted by U)

14

## A set with a determinate number of elements

### Finite Set

15

### Infinite Sets

16

## Two or more sets with at least one common element

### Joint Set

17

## Two or more elements with no common elements

18

## Combines all elements of two sets

### Union

19

##
Given the following:

A = {1, 2, 3}

B = {1, 3, 5}

What is A union B?

### A union B = {1, 2, 3, 5}

20

## Contains only the elements common to both sets

### Intersection

21

##
Given the following:

A = {1, 2, 3}

B = {1, 3, 5}

What is A intersection B?

### Cartesian/Cross Product

26

## What are the two terms used in Relations when identifying ordered pairs?

###
Domain (x-component)

Range (y-component)

27

## A special kind of relation where every element of the domain is related with one and only one element of the range

### Function

28

##
