Domain and Range of Functions

Front

What is the definition of 'Domain' in functions?

Back

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

Front

What is the definition of 'Range' in functions?

Back

The range of a function is the complete set of possible values of the dependent variable (output) that results from using the function.

Front

Identify the domain of the function represented by the set of ordered pairs: (1, 2), (3, 4), (5, 6).

Back

{1, 3, 5}

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

Which of the following sets of ordered pairs represents a function? (1, 2), (1, 3), (2, 4) or (1, 2), (2, 3), (3, 4)?

Back

(1, 2), (2, 3), (3, 4) represents a function.

What is the domain of the function represented by the graph with points (2, 3), (4, 5), (6, 7)?

Back

{2, 4, 6}

What is the range of the function represented by the graph with points (2, 3), (4, 5), (6, 7)?

Back

{3, 5, 7}

Front

Does the set of ordered pairs (1, 2), (2, 3), (2, 4) represent a function?

Back

No, because the input '2' is associated with two different outputs.
