What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y) that the function can produce.

Front

How do you determine the domain from a set of ordered pairs?

Back

The domain can be determined by listing all the unique x-values from the ordered pairs.

Front

How do you determine the range from a set of ordered pairs?

Back

The range can be determined by listing all the unique y-values from the ordered pairs.

Front

What is function notation?

Back

Function notation is a way to represent functions using symbols, typically written as f(x), where f is the function name and x is the input variable.
