## What is an input in a system?

Input is something put into a system or expended in its operation to achieve output or a result. The information entered into a computer system, examples include: typed text, mouse clicks, etc. Output is the information produced by a system or process from a specific input.

## How do you know if a function is input and output?

Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function. Remember, in a function each input has only one output.

## What is input and output in algebra?

The input is the value of x that is applied to the function. The output is the f(x), or the answer that is received as a result of putting x into the function.

## What is input and examples?

The definition of input is something entered into a machine or other system, the act of entering data or other information, or input can also describe giving one’s help, advice or thoughts.

## How can you identify a function?

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

## What is an input in math?

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.

## Which device is both input and output?

For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

## What’s another name for input in math?

a function is defined by its set of inputs, called the domain; a set containing the set of outputs, and possibly additional elements, as members, called its codomain; and the set of all input-output pairs, called its graph.

## How do you do input and output?

The rule for the input-output table below is: add 1.5 to each input number to find its corresponding output number. Use this rule to find the corresponding output numbers. To find each output number, add 1.5 to each input number. Then, write that output number in the table.
