define function?

Answer 1

In mathematics, a function relates each of its inputs to exactly one output. A standard notation for the output of the function f with the input x is f(x). The set of all inputs which a function accepts is called the domain of the function. The set of all outputs is called the range.

For example, the expression f(x) = x2 describes a function, f, that relates each input, x, with one output, x2. Thus, an input of 3 is related to an output of 9. Once a function, f, has been defined we can write, for example, f(4) = 16.

It is a usual practice in mathematics to introduce functions with temporary names like f; in the next paragraph we might define f(x) = 2x+1, and then f(4) = 9. When a name for the function is not needed, often the form y=x2 is used.

Answer 2

The action for which a person or thing is particularly fitted or employed.

Assigned duty or activity.
A specific occupation or role: in my function as chief editor.
An official ceremony or a formal social occasion.
Something closely related to another thing and dependent on it for its existence, value, or significance: Growth is a function of nutrition.
Abbr. f Mathematics.
A variable so related to another that for each value assumed by one there is a value determined for the other.
A rule of correspondence between two sets such that there is a unique element in the second set assigned to each element in the first set.
Biology. The physiological activity of an organ or body part.
Chemistry. The characteristic behavior of a chemical compound, resulting from the presence of a specific functional group.
Computer Science. A procedure within an application.

Answer 3

(1) In programming, a named section of a program that performs a specific task. In this sense, a function is a type of procedure or routine. Some programming languages make a distinction between a function, which returns a value, and a procedure, which performs some operation but does not return a value.
Most programming languages come with a prewritten set of functions that are kept in a library. You can also write your own functions to perform specialized tasks.

(2) The term function is also used synonymously with operation and command. For example, you execute the delete function to erase a word.

In mathematics, a function relates each of its inputs to exactly one output. A standard notation for the output of the function f with the input x is f(x). The set of all inputs which a function accepts is called the domain of the function. The set of all outputs is called the range.

Answer 5

In common parlance, as well as in engineering, function denotes a property of something, and which is used/applied for an objective/goal/purpose/scope.

Answer 6

Let us assume that we have two sets A and B .
A function from set A to set B exists only if there is a relation from each and every element in set A to atleast one element in set B

Answer 7

Let A and B be sets. A function from A to B is a subset F of AxB such that for each x in A there is a unique y in B such that (x,y) is in F.

Answer 8

Here's a few definitions to choose from. Just got to google and type in "define:"then the word you need without the quotations.

Answer 9

Function is an act performed by someone and relished by someothers.

Answer 10

the function is defined by a domaine, a codomaine and a definiton law....wich tooks one element from the domaine and it puts it into one (and one only) element from the codomaine
