Domain of a function
set theory, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined. That
Function (mathematics)
of a set X, the domain of the function, to a single element y of another set Y (possibly the same set), the codomain of the function. If the function
Differentiable function
calculus (a branch of mathematics), a differentiable function of one real variable is a function whose derivative exists at each point in its domain. As a result
Partial function
called a total function and is equivalent to a function. Partial functions are often used when the exact domain, X, is not known (e.g. many functions in computability
Domain may refer to: Domain (taxonomy), a taxonomic subdivision larger than a kingdom Domain name, the name of a realm of administrative autonomy, authority
Graph of a function
mathematics, the graph of a function f is, formally, the set of all ordered pairs (x, f(x)), such that x is in the domain of the function f, and, in practice
Domain of unknown function
A domain of unknown function (DUF) is a protein domain that has no characterised function. These families have been collected together in the Pfam database
Convex function
to zero for its entire domain then the function is convex. Well-known examples of convex functions include the quadratic function x 2 {\displaystyle x^{2}}
Argument of a function
to have a domain consisting of ordered pairs or tuples of argument values. The argument of a circular function is an angle. The argument of a hyperbolic
x ranges over the elements of the domain X, is called the image of f. In general, the image of a function is a subset of its codomain. Thus, it may not
