Definitions
computer programming
Functions in computer programming are self-contained blocks of code that perform a specific task. They are reusable and help in organizing code efficiently.
Synonyms
method, procedure, subroutine.
Examples of usage
- Please create a function to calculate the average of a list of numbers.
- The main function of this program is to sort the data in ascending order.
mathematics
In mathematics, a function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.
Synonyms
Examples of usage
- The function f(x) = 2x + 3 represents a linear equation.
- This function maps each input to a unique output.
general
To function means to work or operate in a particular way. It can also refer to performing a specific duty or role.
Synonyms
Examples of usage
- The new machine functions much more efficiently than the old one.
- Despite the challenges, the team continued to function effectively.

Interesting Facts
Mathematics
- In math, a function takes one number (input), does something to it, and gives back another number (output).
- A function can be represented in different ways: through equations, graphs, or even tables.
- Functions can be linear, quadratic, or exponential, revealing different patterns of how numbers change.
Computer Science
- In programming, functions help organize code, allowing programmers to reuse blocks of code for efficiency.
- Functions in programming can take input parameters and return values, similar to their mathematical counterparts.
- There are different types of functions in programming, including built-in functions (like print) and user-defined functions.
Biology
- Every organ in the body has specific functions, such as the heart pumping blood or the lungs helping with breathing.
- Cells perform different functions based on their type, like muscle cells contracting or nerve cells transmitting signals.
- Functions of ecosystems include providing habitats, producing oxygen, and cycling nutrients.
Linguistics
- In language, functions refer to the roles words or phrases play in a sentence, like subject, verb, or object.
- Pragmatics studies the functions of language in context, helping us understand meaning beyond just words.
- Different languages may emphasize different functions, changing how thoughts are expressed and understood.
Economics
- Functions in economics describe relationships between variables, such as supply and demand impacting prices.
- Production functions illustrate how factors of production (like labor and capital) combine to create goods.
- Utility functions represent consumer preference, showing how choices are made based on satisfaction.
Origin of 'functions'
The word 'function' originated from the Latin word 'functio', meaning 'performance' or 'execution'. It has been used in various fields such as mathematics, computer programming, and general language to describe the operation or role of something. The concept of functions has evolved over time to become a fundamental aspect of problem-solving and organization in different disciplines.
