What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-values) for which the relation is defined.

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from the relation.

How do you find the domain of a given relation?

Back

To find the domain, identify all the first elements (x-values) in the ordered pairs of the relation.

How do you find the range of a given relation?

Back

To find the range, identify all the second elements (y-values) in the ordered pairs of the relation.

What is the vertical line test?

Back

The vertical line test is a method to determine if a relation is a function by checking if any vertical line intersects the graph of the relation at more than one point.
