codomain englanniksi

  1. The target set into which a function is formally defined to map elements of its domain; the set denoted ''Y'' in the notation ''f'' : ''X'' → ''Y''.

  3. Definition 2.5. ''A function is onto if each element of the codomain has at least one element of the domain assigned to it. In other words, a function is onto if the range equals the codomain.''

  5. Once we have described f as a function from A to B, by convention we will call B the ''codomain'', even though other sets, of which B is a subset, could have been used.(..)If y is an element of the codomain, then y\in\mathit{Img}(f,A) iff there is some x in the domain such that f maps x to y.

  7. For example, the codomain of g(X) = X^3 consists of all real numbers. A function links each element in its domain to some element in its codomain. Each domain element is linked to exactly one codomain element.
