Understanding Binary Relations

What is a binary relation between two sets?

• A process to sort elements within a single set

• A technique to divide a set into two subsets

• A method to relate elements of one set to elements of another set

• A way to combine elements of two sets into a single set

In a binary relation, what does the set L represent?

• A set of ordered pairs representing the relation

• A set of unrelated elements

• The union of two sets

• The intersection of two sets

What is the domain of a binary relation?

• The set of all elements in both sets

• The set of all elements in the second set

• The set of all elements in the first set

• The set of all elements in the first set related to elements in the second set

How can binary relations on the set of real numbers be visually represented?

• Using pie charts

• Using Cartesian coordinates

• Using Venn diagrams

• Using bar charts

What is a scatter plot?

• A graph of finite sets of ordered pairs

• A graph of infinite sets of ordered pairs

• A method to calculate the average of a set

• A technique to find the median of a set
