SECTION 2.3 If f : X → Y is a function, we say that X is the domain

... If f : X → Y is a function, we say that X is the domain, and Y is the co-domain. The range of f is defined as the set f (X) = {y ∈ Y | ∃x ∈ X, f (x) = y}. In general, if A ⊆ X is a subset of X, we define the image of A as the set f (A) = {y ∈ Y | ∃x ∈ A, f (x) = y}. The image of a set A is oftentime ...

... X is not path-connected. Indeed, assume to the contrary that there exists a path γ : [0, 1] → X with γ(0) = ( π1 , 0) and γ(1) = (0, 0). Let c = inf {t ∈ [0, 1] | γ(t) ∈ X1 } . Then γ([0, c]) contains at most one point of X1 , while γ([0, c]) contains all of X1 . So γ([0, c]) is not closed, and ther ...

Continuous function

In mathematics, a continuous function is, roughly speaking, a function for which small changes in the input result in small changes in the output. Otherwise, a function is said to be a discontinuous function. A continuous function with a continuous inverse function is called a homeomorphism.Continuity of functions is one of the core concepts of topology, which is treated in full generality below. The introductory portion of this article focuses on the special case where the inputs and outputs of functions are real numbers. In addition, this article discusses the definition for the more general case of functions between two metric spaces. In order theory, especially in domain theory, one considers a notion of continuity known as Scott continuity. Other forms of continuity do exist but they are not discussed in this article.As an example, consider the function h(t), which describes the height of a growing flower at time t. This function is continuous. By contrast, if M(t) denotes the amount of money in a bank account at time t, then the function jumps whenever money is deposited or withdrawn, so the function M(t) is discontinuous.
