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).
Discrete Function vs Continuous Function. Functions are one of the most important classes of mathematical objects, which are extensively used in almost all sub fields of mathematics. As their names suggest both discrete functions and continuous functions are two special types of functions. A function is a relation between two sets defined in such a way that for each element in the first set, the value that corresponds to it in the second set is unique.
