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 .

What is the domain?

• {2002, 2003, 2004, 2005}

• {0.75, 1.5, 2.25, 2.5}
