Functions, Domain, & Range SOL Review

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for a function.

Front

Identify the domain of the relation: {(-3, 14), (-1, 32), (2, 38), (4, 44)}.

Back

{-3, -1, 2, 4}.

Front

Identify the range of the relation: {(-3, 14), (-1, 32), (2, 38), (4, 44)}.

Back

{14, 32, 38, 44}.

Front

What does it mean for a relation to NOT be a function?

Back

A relation is not a function if at least one input (x-value) is associated with more than one output (y-value).

Front

Which of the following is NOT in the domain of the relation: {(-3, 14), (-1, 32), (0, 38), (3, 44)}?

Back

-3.

Front

What is an example of a function?

Back

An example of a function is f(x) = 2x + 3, where each x-value has one corresponding y-value.

Front

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

Back

An example is {(1, 2), (1, 3)}, where the input 1 has two different outputs.

Front

How do you determine the domain from a graph?

Back

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