Wiki User
∙ 13y agoIt is a functional relationship which has an input and an output. Addition, subtraction, multiplication, division, reciprocals, exponentials, logarithms are all examples.
It is a injective relationship. However, it need not be surjective and so will not be bijective. It will, therefore, not define an invertible function.
There need not be any relationship.
A function.

A one-to-one or injective function.
The relationship is called a surjection or a surjective function.

Output from what? Of a mathematical function? Of a computer procedure? Of a machine? Of a river? And what type of output? Please clarify your question.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
A transfer function is a mathematical representation of the relationship between the input and output of a system in the frequency domain. It describes how the system responds to different frequencies and can be used to analyze and design control systems.
There need not be any relationship.
The relationship between two variables is called a relation. A relation in which a set of input values maps onto a set of output values such that each input corresponds to at most one output is called a "function." Functions do not necessarily have to be lines; they do not even have to be exponential, or parabolic, or continuous. A bunch of scattered points or lines that meets the requirements can still be considered a function involving two variables.
