difference between relations and functions
Relations vs Functions. In mathematics, relations and functions include the relation between two objects in a certain order. Both are different. Take, for instance, a function. A function is linked with a single quantity. It is also associated with the argument of the function, input, and value of the function, or otherwise known as the input.
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 XÃY, is a set of ordered pairs consisting of elements from the two sets, often denoted as (x,y).
