Domain and Range

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

Identify the domain of the function represented by the set {-2, -1, 0, 1, 8}.

Back

{-2, -1, 0, 1, 8}

Front

Identify the range of the function represented by the set {-4, 0, 1, 3}.

Back

{-4, 0, 1, 3}

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, where each pair consists of an input (x) and an output (y).

Front

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

Back

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

Front

Given the relation (3,0), (7,0), (3,5), (7,5), what is the domain?

Back

{3, 7}

Front

Given the relation (3,0), (7,0), (3,5), (7,5), what is the range?

Back

{0, 5}

Front

What is the greatest value in the range for the function y = -2x + 4 when the domain is {-5, -1, 5, 1}?

Back

14

Front

How do you find the range of a function from a table of values?

Back

Evaluate the function for each input value and collect all the resulting output values.
