Functions create shortcut formulas for the user: Sum (auto addition) and Avg (auto averaging of numbers).; A special formula that does not use operators to calculate a result

A relationship between two sets of numbers or other mathematical objects where each member of the first set is paired with only one member of the second set. Functions can be used to understand how one quantity varies in relation to (is a function of) changes in the second quantity. For example, there is a functional relationship between the price per pound of a particular type of meat and the total amount paid for ten pounds of that type of meat.

Built-in calculations that can save you time when entering complex formulas in a spreadsheet program.

in its mathematical sense expresses how things are related; also refers to what something does, how it works or operates.

Identifies the relationship within every combination of input conditions that will achieve one unique output. For example, in electronic circuits an "AND function" will be achieved only if all inputs are valid.

A predefined operation that performs mathematical, logical, statistical, financial, and character-string operations on data in a spreadsheet or a database.

a entity which acts upon an input to produce an output; an equation

a mathematical expression. In the case of spreadsheets, a function always starts with the equals sign, =. Examples: =SUM(e12:h22) =COUNT(b14:g36) =AVERAGE(A4,A6,A12,A42)

mathematical relationship The expresion y = f(x) means that is a function of . Therefore if I know , I can calculate because I know the formula that describes the mathemetical way that is related to

a one-to-one relation where the input gives a predictable result, i.e. you will get this result every time using that input.

In mathematics, a transform that accepts one or more inputs and produces one output. In computer science, an implementation of such a function. Inputs and outputs may be numbers, character strings, or any other data representation.

The procedure which causes a certain action on a given set of input.

Functions are premade formulas that assist in the development of your spreadsheet. In a function, you name the formula to be calculated and then supply the inputs or arguments.

A relationship between two sets of numbers (or other mathematical objects). Functions can be used to understand how one quantity varies in relation to another, for example, the relationship between the number of cars and the number of tires.

Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order, or structure. Functions can be used to perform simple or complex calculations. The structure of a function begins with an equal sign (=), followed by the function name (such as SUM, AVERAGE, etc.), an opening parenthesis, the arguments for the function separated by commas, and a closing parenthesis.

A predefined formula that performs a specific operation in Excel.

Performs or is able to perform one or more actions in response to user input.

A predefined relation built into the spreadsheet program that can be used as a formula for such purposes as averaging numbers or finding the maximum value in a group of cells.

A formula for making a certain kind of calculation, such as MAX, AVERAGE, MIN

Mathematical relationship between two quantities y and x, given as an equation. y=f(x)

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 that a function accepts is called the domain of the function.
