Domain and Range

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that result from using the function.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that can be used in the function.

Front

Identify the range of the following set of points: (0, 1), (2, 3), (4, 5).

Back

{1, 3, 5}

Front

Identify the domain of the following set of points: (0, 1), (2, 3), (4, 5).

Back

{0, 2, 4}

Front

What is the range of the function f(x) = x^2 for x in the domain of all real numbers?

Back

The range is {y | y >= 0}.

Front

What is the domain of the function f(x) = 1/x?

Back

The domain is all real numbers except x = 0.

Front

If the domain of a function is {-4, -1, 0, 2, 7}, what is the range if the function outputs are {3, 5, 7, 9}?

Back

The range is {3, 5, 7, 9}.

Front

What does it mean if a function is not defined for certain x-values?

Back

It means those x-values are not included in the domain of the function.

Front

How do you find the range from a graph of a function?

Back

Look at the y-values that the graph reaches; the range is the set of these y-values.

Front

What is the range of the function f(x) = -x + 2?

Back

The range is all real numbers.
