UNIT 3 FUNCTIONS REVIEW

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 based on its domain.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) is associated with exactly one output (y-value).

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

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

Back

The domain can be determined by identifying the x-values that the graph covers.

Front

What is the difference between domain and range?

Back

The DOMAIN refers to the set of input values (x-values), while the RANGE refers to the set of output values (y-values) of a function.

Front

What does it mean if a function has multiple y-values for a single x-value?

Back

If a function has multiple y-values for a single x-value, it is not a function.

Front

What is an example of a function?

Back

Front

What is an example of a relation that is not a function?

Back

An example of a relation that is not a function is the set of points {(1,2), (1,3)}, where the x-value 1 corresponds to two different y-values.

Front

How do you express the domain of a function in interval notation?

Back

The domain can be expressed in interval notation, such as [1, 9] for x-values between 1 and 9 inclusive.
