What is the definition of a relation

The video tutorial explains the concept of relations in mathematics, highlighting the difference between relations and functions. It describes four methods to represent relations: ordered pairs, mapping, tables, and graphing. Each method is explained in terms of how it shows the relationship between input and output values, with examples provided for clarity.

What is a relation in mathematics?

• A set of ordered pairs

• A relationship between an input and an output

• A type of function

• A mathematical equation

Which of the following is NOT a way to represent relations?

• Equations

• Tables

• Mapping

• Ordered pairs

In mapping, what do the X values represent?

• Neither input nor output

• Both input and output

• Input

• Output

How can graphing help in understanding relations?

• By showing the relationship between plotted points

• By providing a list of ordered pairs

• By mapping inputs to outputs

• By creating a table of values

What is the primary purpose of using tables in representing relations?

• To show the relationship between inputs and outputs

• To map inputs to outputs

• To graph the relation

• To list all possible outputs
