Directions: Select all correct answer(s).

Identify all of the true statements.

• All relations are functions, but not all functions are relations.

• All functions are relations, but not all relations are functions.

• In any set of ordered pairs, the second coordinate is called the domain.

• A function is a relation between a set of inputs and a set of outputs with the property that each input is related to exactly one output.
