These valves are quick opening and provide a very tight closure on ...

Representing Functions And Relations Nroc

A function is a relation in which one variable specifies a single value of another variable. For example, when you toss a ball, each second that passes has one and only one corresponding height. Time only goes forward, and never repeats itself. The height of the ball depends on how much time has passed since it left your hand.
