Stage 2
Duration: 4 hours
Modality: In class (2 h) and at home (2h)
Purpose:
Do an investigation about the ways in which a relation and a function can be represented.
Instructions:
1.Form teams of 4 students.
2. At home, investigate o Internet and/or math books, the ways that a relation and a function can be represented. You can consult the chapter 1 of the book Mathematics 3,DENMS, UANL.
3. You will consult the following concepts and give a definition and/or description of each one:
Variable
A variable is a value that may change within the scope of a given problem orset of operations.
In algebraic expressions, letters represent variables. These letters are actually numbers in disguise. We call these letters "variables" because the numbers they represent can vary,that is, we can substitute one or more numbers for the letters in the expression.
Constant
A constant is a value that remains unchanged, though often unknown or undetermined.
Constants are theterms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables inthe term that can change its value.
Set
A set is a collection of distinct symbols unordered objects. Sets are typically collections of numbers, though a set may contain any type of data(including other sets).The objects in a set are called the members of the set or the elements of the set.
Element of the set
A number, letter, point, line, or any other object contained in a set. Forexample, the elements of the set {d, e, g} are the letters d, e, and g.
Set of numbers
It is a group or a collection of numbers.
Ordered pairs of numbers
Two numbers written in a certainorder. They are usually written in parentheses like this: (2, 6). Can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second....
