Back

The domain is \{2, 4, 6\}.

Front

Define a function in mathematics.

Back

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

Front

What is the difference between domain and range?

Back

The domain is the set of all possible input values, while the range is the set of all possible output values.

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input corresponds to exactly one output.

Front

What does it mean to factor a polynomial?

Back

Factoring a polynomial means expressing it as a product of its factors.

Front

What is a trinomial?

Back

A trinomial is a polynomial with three terms.
