Functions whose domain are the nonnegative integers, known as sequencesare often defined by recurrence relations. In this case, an element x of the domain is represented by an interval of the x -axis, and the corresponding value of the function, f xis represented by a rectangle whose base is the interval corresponding to x and whose height is f x possibly negative, in which case the bar extends below the x -axis. Practical applications of functions whose variables are complex numbers are not so easy to illustrate, but they are nevertheless very extensive. Learn more.

All functions can be described by sets of pairs but it may not be practical to construct a diagram for functions between other sets such as sets of matrices. Parts of this may create a plot that represents parts of the function. A function is a relation that uniquely associates members of one set with members of another set.
In the definition of function, X and Y are respectively called the domain and the codomain of the function f. If (x, y) belongs to the set.

Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given. of values at which a function is defined is called its domain, while the set f(A) as it is not uncommon for the term map to denote a function with some sort of.
