Roster Method & Set-Builder Notation...1

College Algebra
Chapter 1/Section 1
Review

We begin our College Algebra journey with a review of the basics according to the author of the textbook.

Working with sets.

There are two methods for denoting sets:

•Roster Method
•Set-Builder Notation

Knowing what I know about these methods, I will make up two sets. Tell me what you think.

Let B = the set of the four gospels

Using the Roster Method, I would write

B = {Matthew, Mark, Luke, John}

Is this right?

Using the Set-Builder Notation, I would write

B = { x|x is the four gospels }

Is this right?

 

B = { x| x =gospel }

 

Is that your way to write set B or the only correct way?

 

my way to write set B

 

That's what I thought.
