(U) Domain and Range Part II

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

What does it mean if the domain is all real numbers?

Back

It means that any real number can be used as an input for the function.

Front

Back

It implies that the function is only defined for non-negative values of x.

Front

What is the significance of the range being all real numbers?

Back

It indicates that the function can produce any real number as an output.

Front

Back

It means that the output values of the function can be any number less than or equal to 4.

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 exists.

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.

Front

What is a common restriction on the domain of a function?

Back

A common restriction is that the denominator of a fraction cannot be zero.

What is an example of a function with a restricted domain?
