## Whats a function and not a function?

A function is a relation in which each input has only one output.

: y is a function of x, x is not a function of y (y = 9 has multiple outputs).

…

: y is not a function of x (x = 1 has multiple outputs), x is not a function of y (y = 2 has multiple outputs)..

## What does a function look like on a table?

A function table displays the inputs and corresponding outputs of a function. Function tables can be vertical (up and down) or horizontal (side to side). In this lesson, we are using horizontal tables.

## Does the input output table represent a function?

A function is a relation where there is only one output for every input. In other words, for every value of x, there is only one value for y. An input-output table is a table that shows how a value changes according to a rule.

## What is the input and output of a function?

In mathematics, a function is any expression that produces exactly one answer for any given number that you give it. The input is the number you feed into the expression, and the output is what you get after the look-up work or calculations are finished.

## What is a function rule example?

A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3.

## What is a function table?

A function table displays the relationship between the inputs and outputs of a specified function. A function table will also follow the rules of a function in that every input only produces one output.

## What is input and output in math definition?

In mathematics, input and output are terms that relate to functions. Both the input and output of a function are variables, which means that they change. You can choose the input variables yourself, but the output variables are always determined by the rule established by the function.

## What is the rule of a function table?

A function table has values of input and output and a function rule. In the function rule, if we plug in different values for the input, we get corresponding values of output. There is always a pattern in the way input values x and the output values y are related which is given by the function rule.

## When the input is what is the output?

An input is data that a computer receives. An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised.

## What is the rule for the pattern of numbers?

A numbers pattern is a sequence of numbers that grows or repeats according to a specific rule. For example, the following number pattern starts at 2 and follows the rule add 3: 2, 5, 8, 11, 14….and so forth.
