Unit 3 Lesson 1Are We Relations?Demonstrating Mastery
This Unit 3 Lesson 1 Are we relations?1Content StandardYou will
be able to understand that a function is a rule that assigns to
each input exactly one output. The graph of a function is the set
of ordered pairs consisting of an input and the corresponding
output.(Relations)

This lesson will help you understand that relations are made up
of a sets of ordered pairs . These ordered pairs have both an input
value and an output value.2Defining Success for Lesson 1Once you
have completed this lesson, you will be able to:
#1 Define the
terms:RangeRelationX-ValuesInputDomainY-ValuesOutput
Once you have completed Lesson 1, you will have mastered 4 main
skills. The first is to define the following terms: range, domain,
relation, input, output, x-values and y-values.3Defining Success
for Lesson 1Once you have completed this lesson, you will be able
to:
#2 Identify the various forms of a relation:
MappingSetGraphTable
Next you will be able to identify the different forms of a
relation which are mappings, graphs, sets and tables.4Defining
Success for Lesson 1Once you have completed this lesson, you will
be able to:
#3 Represent a relation in the various forms:
MappingSetGraphTable
In addition you will master representing any relation as a map,
a graph , as a table and as a set.5Change the word "is" to the word
"in"Defining Success for Lesson 1Once you have completed this
lesson, you will be able to:
#4 Identify the domain and range of a relation presented in
different forms.
And finally once you have completes this lesson you will be able
to successfully identify the domain and range of any relation in
any form.6XY23-185-705-30TableGraphDomain is {2,-1,5,0,-3} Range is
{3,8,-7,5,0}
Here we have examples of a relation in table and in graphic
forms. The domain and range are also
listed.7{(2,3),(-1,8),(5,-7),(0,5),(-3,0)}Set-3-1025-70358MappingDomain
is {2,-1,5,0,-3}Range is {3,8,-7,5,0}
Here you see an example of a relation in the form of a set and a
mapping, each with the domain and range given.8Unit 3 Lesson 1Are
