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).
A function is an equation for which any x that can be plugged into the equation will yield exactly one y out of the equation. There it is. That is the definition of functions that weâre going to use and will probably be easier to decipher just what it means. function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Okay, that is a mouth full. Letâs see if we can figure out just what it means.
