Front

What is a relation in mathematics?

Back

A set of ordered pairs, where each pair consists of an input and an output.

Front

How do you find the range of a set of ordered pairs?

Back

Front

How do you find the domain of a set of ordered pairs?

Back

List all the first elements (x-values) from each ordered pair.

Front

What does it mean if a function is defined as f(x)?

Back

It means that for every input x, there is a corresponding output f(x).

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

If a function has a domain of {1, 2, 3}, what can you say about its range?

Back

The range can vary, but it must consist of outputs corresponding to the inputs 1, 2, and 3.

Front

What is an example of a function with a domain of {0, 1, 2} and a range of {1, 2}?

Back

f(0)=1, f(1)=2, f(2)=1 is one possible function.

Front

What is the notation for domain and range?

Back

Domain is often denoted as D and range as R.
