Domain and Range

Front

What is the domain of a function?

Back

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

How do you determine the domain of a graph?

Back

To determine the domain of a graph, identify the x-values that the graph covers. Look for any restrictions such as vertical asymptotes or holes.

Front

Back

It means that the function is defined for all x-values less than or equal to 1.

Front

Back

It means that the output values of the function are all less than or equal to 4.

Front

What is the domain of the function defined by the points {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The domain is {-4, 0, 1, 2}.

Front

What is the range of the function defined by the points {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The range is {-4, -3, 1}.

Front

Back

This indicates that x can take any value greater than -3 and up to and including 5.

Front

Back

The domain includes all x-values greater than or equal to -3.

Front

How do you express the domain of a function using set notation?

Back

The domain can be expressed in set notation, for example, D = {x | x < 1}.
