2. Truncus (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Truncus_(mathematics)

   Truncus (mathematics) In analytic geometry, a truncus is a curve in the Cartesian plane consisting of all points (x, y) satisfying an equation of the form. A mathematical graph of the basic truncus formula, marked in blue, with domain and range both restricted to [-5, 5]. where a, b, and c are given constants.

3. Domain of a function - Wikipedia

   en.wikipedia.org/wiki/Domain_of_a_function

   In mathematics, the domain of a function is the set of inputs accepted by the function. It is sometimes denoted by or , where f is the function. In layman's terms, the domain of a function can generally be thought of as "what x can be". [1] More precisely, given a function , the domain of f is X. In modern mathematical language, the domain is ...

4. Image (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Image_(mathematics)

   In mathematics, for a function , the image of an input value is the single output value produced by when passed . The preimage of an output value is the set of input values that produce . More generally, evaluating at each element of a given subset of its domain produces a set, called the " image of under (or through) ".

5. Function (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Function_(mathematics)

   In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. [ 1 ] The set X is called the domain of the function [ 2 ] and the set Y is called the codomain of the function. [ 3 ] Functions were originally the idealization of how a varying quantity depends on another quantity.

6. Range of a function - Wikipedia

   en.wikipedia.org/wiki/Range_of_a_function

   In mathematics, the range of a function may refer to either of two closely related concepts: the codomain of the function, or. the image of the function. In some cases the codomain and the image of a function are the same set; such a function is called surjective or onto. For any non-surjective function the codomain and the image are different ...

7. Mathematics - Wikipedia

   en.wikipedia.org/wiki/Mathematics

   Mathematics has developed a rich terminology covering a broad range of fields that study the properties of various abstract, idealized objects and how they interact. It is based on rigorous definitions that provide a standard foundation for communication. An axiom or postulate is a mathematical statement that is taken to be true without need of ...

8. Surjective function - Wikipedia

   en.wikipedia.org/wiki/Surjective_function

   In mathematics, a surjective function (also known as surjection, or onto function / ˈɒn.tuː /) is a function f such that, for every element y of the function's codomain, there exists at least one element x in the function's domain such that f(x) = y. In other words, for a function f : X → Y, the codomain Y is the image of the function's ...

9. Integer - Wikipedia

   en.wikipedia.org/wiki/Integer

   The integers arranged on a number line. An integer is the number zero (0), a positive natural number (1, 2, 3, . . .), or the negation of a positive natural number (−1, −2, −3, . . .). [ 1 ] The negations or additive inverses of the positive natural numbers are referred to as negative integers. 2 The set of all integers is often denoted ...
