What is the range of a function?

Back

The range is the set of all second coordinates (or y-values) of a relation or function.

How can you identify the domain from a set of ordered pairs?

Back

The domain can be identified by listing all the first coordinates (x-values) from the ordered pairs.

Front

What is the difference between domain and range?

Back

The domain consists of the x-values, while the range consists of the y-values of a relation or function.

What is an example of a function?

Back

A function is a specific type of relation where each input (x-value) is paired with exactly one output (y-value). For example, f(x) = 2x + 3.
