Thread: Ordered pair of function

Are you comfortable with the definitions of function, domain and range? Can you write them from memory and can you give counterexamples, i.e., something that is not a function, a set that is not the domain of a given function and a set that is not the range of a given function? If you are not comfortable with definitions and examples, you should go back to the textbook or lecture notes and read them again.
