Domain and Range

Front

What is the definition of Domain in a function?

Back

The set of all possible input values (x-values) for a function.

Front

What is the definition of Range in a function?

Back

The set of all possible output values (y-values) for a function.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {0, 1, 2, -4}.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {1, -3, -4}.

Front

What are the y-values in a function called?

Back

Range.

Front

What is the range of the graph represented by -3 ≤ y < 1?

Back

The range includes all y-values from -3 up to, but not including, 1.

Front

What is the range of the graph represented by -3 ≤ y ≤ 3?

Back

The range includes all y-values from -3 to 3, including both endpoints.

Front

What is the range of a function that outputs all real numbers?

Back

The range is all real numbers.

Front

If a function has a domain of {1, 2, 3}, what can be said about its range?

Back

The range can vary; it depends on the outputs corresponding to the inputs.

Front

What does it mean if a function's range is limited to positive numbers?

Back

It means the function only outputs values greater than zero.
