Added Aug 1, 2010 by ihsankhairir in Mathematics. Your vertical A mapping diagram represents a function if each input value is paired with only one output value. It will also generate a step by step explanation for each operation. If there is only one y value for an x value it is a function. The domain calculator allows you to take a simple or complex function and find the domain in both interval and set notation instantly. An ordered pair, commonly known as a point, has two components which are the x and y coordinates. (Warning: This means that, while all functions are relations, since they pair information, not all relations are functions.
