Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

What is a one-to-one function?

Back

A one-to-one function is a function where each output is associated with exactly one input.
