Front

What is the definition of a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the domain of a relation?

Back

The domain is the set of all x-values in a relation.

Front

What is the range of a relation?

Back

The range is the set of all y-values in a relation.

Front

Does the graph represent a function if a vertical line intersects it at more than one point?

Back

No, it does not represent a function.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point in a coordinate system.

Front

What is the difference between domain and range?

Back

Domain refers to the set of x-values, while range refers to the set of y-values.

Front

What does it mean if a relation is not a function?

Back

It means that at least one x-value is associated with more than one y-value.

Front

How can you determine the domain from a graph?

Back

The domain can be determined by identifying all the x-values that the graph covers.

Front

How can you determine the range from a graph?

Back

The range can be determined by identifying all the y-values that the graph covers.

Front

What is a relation in mathematics?

Back
