Domain, Range, Function

Front

What is a function?

Back

A function is a relation where every input has only ONE output.

Front

What is the range of a function?

Back

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

Front

What are the inputs of a function called?

Back

The inputs of a function are called the domain.

Front

What is the domain of the relation {(1,2), (3,4), (5,6)}?

Back

The domain is {1, 3, 5}.

Front

What is the range of the relation {(1,2), (3,4), (5,6)}?

Back

The range is {2, 4, 6}.

Front

Identify the domain of the relation {(0,1), (1,-3), (2,-4), (-4,1)}.

Back

Domain: {-4, 0, 1, 2}.

Front

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

Back

Range: {-4, -3, 1}.

Front

What is the definition of domain?

Back

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

Front

What is the difference between a relation and a function?

Back

A relation can have multiple outputs for a single input, while a function has only one output for each input.

Front

If a function has the relation {(2,3), (2,4)}, is it a function?

Back

No, it is not a function because the input 2 has two different outputs (3 and 4).
