In other words it is not a function because it is not single valued A Benefit of Ordered Pairs You could set up the relation as a table of ordered pairs. This tutorial will introduce you to ordered pairs! Keywords: Background Tutorials. map (function (num) {return num * 2;}); // Array [2, 8, 18] Funktionen teilen einen Namen mit einer existierenden Eigenschaft. In general, the functionality of something refers to the overall quality and how well something performs. For example-- and let me look at a visual way of thinking about a function this time, or a relationship, I should say-- let's say that's our y-axis, and this right over here is our x-axis. Calculus. Description =IF(AND(A2>0,B2<100),TRUE, FALSE) IF A2 (25) is greater than 0, AND B2 (75) is less than 100, then return TRUE, otherwise return FALSE.

The Excel NOT function returns the opposite of a given logical or boolean value. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like.
