Domain And Range

Front

What is the definition of 'domain' in 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 definition of 'range' in 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 function {(0,1), (1,-3), (2,-4), (-4,1)}.

Back

D: {0, 1, 2, -4}

Front

Identify the range of the function {(0,1), (1,-3), (2,-4), (-4,1)}.

Back

R: {1, -3, -4}

Front

What is the domain of the graph represented by the points (3,5), (3,7), (0,5), (0,3)?

Back

D: {3, 0}

Front

What is the range of the graph represented by the points (3,5), (3,7), (0,5), (0,3)?

Back

R: {5, 7, 3}

Front

Which of the following is not an element of the domain: {0, 1, 2, 3}?

Back

0 is not an element of the domain.

Front

If a function has a domain of {3,7} and a range of {0,5}, which of the following is a valid relation?

Back

(3,0), (7,0), (3,5), (7,5) is a valid relation.

Front

What does it mean if a function's range is 'All Real Numbers'?

Back

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

Front

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

Back

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