Domain and Range Review

Front

What is the definition of Domain in a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) for which the function is defined.

Front

What is the definition of Range in a function?

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that result from using the function.

Front

How do you determine the domain of a function from its graph?

Back

The domain can be determined by identifying the x-values for which the graph has points. It includes all x-values that the graph covers.

Front

What does it mean if a function has a domain of all real numbers?

Back

It means that the function is defined for every possible value of x, without any restrictions.

Front

What does it mean if a function has a restricted domain?

Back

It means that there are specific values of x that are not included in the domain, often due to vertical asymptotes or holes in the graph.

Front

Back

The domain is the set of all x-values from -4 to 1, including -4 but not including 1.

Front

Back

The domain is all x-values greater than or equal to 4.

Front

What is the range of a function?

Back

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

Front

How do you determine the range of a function from its graph?

Back

The range can be determined by identifying the y-values that the graph reaches. It includes all y-values that the graph covers.

What does it mean if a function has a range of all real numbers?

Back

It means that the function can produce every possible value of y, without any restrictions.
