From high school mathematics onwards, function becomes a common term. Even though it is used quite often, it is used without proper understanding of its definition and interpretations. This article focuses on describing those aspects of a function. Relation. A relation is a link between the elements of two sets. In a more formal setting, it can be described as a subset of the Cartesian product of two sets X and Y. Cartesian Product of X and Y, denoted as XÃY, is a set of ordered pairs consisting of elements from the two sets, often denoted as (x,y).
2.3 Functions. Definition: A relation is any set of ordered pairs; such as <:4, F1;,:2,3;,:0,5;,:2,7;,:3,9;=. If the value of the second coordinate, y, depends on the value of the first coordinate, x, then y is. the dependent variable and x is the independent variable.
