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.

Front

Identify the domain of the graph represented by the set {-4 ≤ x ≤ 2}.

Back

The domain is all x-values from -4 to 2, inclusive.

Front

Identify the range of the graph represented by the set {0, 6, 12, 18}.

Back

The range consists of the output values 0, 6, 12, and 18.

Front

What does the notation -3 ≤ y < 1 represent?

Back

This notation indicates that y can take any value from -3 to just below 1, including -3 but not including 1.

Front

If a function has a domain of {-5 ≤ x ≤ 4}, what does this mean?

Back

This means that the function is defined for all x-values from -5 to 4, inclusive.

Front

What is the difference between domain and range?

Back

Domain refers to the input values (x-values), while range refers to the output values (y-values) of a function.

Front

How do you find the domain of a graph?

Back

To find the domain of a graph, identify the x-values that the graph covers.

Front

How do you find the range of a graph?

Back

To find the range of a graph, identify the y-values that the graph covers.

Front

What is an example of a domain in set notation?

Back

An example of a domain in set notation is {-2 ≤ x ≤ 4}.
