A function is when one variable or term depends on another according to a rule. There is a special relationship between the two variables of the function where each value in the input applies to only one value in the output. These rules are called function rules, because they explain how the function operates.

What is an input device give examples?

In computing, an input device is a piece of computer hardware equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, digital cameras and joysticks.

What is both an input and an output device?

Typical output devices in a computer system are the monitor, speakers and the printer. Some devices that perform both input AND output operations are referred to as I/O (input/output) devices and their operations are called I/O operations. Examples of common input and output components are disk drives and modems.

## What are inputs and outputs in economics?

Resources such as people, raw materials, energy, information, or finance that are put into a system (such as an economy, manufacturing plant, computer system) to obtain a desired output. Inputs are classified under costs in accounting.

## What is the output of the function?

An output function is a function that an optimization function calls at each iteration of its algorithm. Typically, you use an output function to generate graphical output, record the history of the data the algorithm generates, or halt the algorithm based on the data at the current iteration.

## Is the Y the input or output?

A function is an equation which shows the relationship between the input x and the output y and where there is exactly one output for each input. Another word for input is domain and for output the range.

## Can an input have two different outputs?

Each input has only one output, and the fact that it is the same output (4) does not matter. Remember that in a function, the input value must have one and only one value for the output. There is a name for the set of input values and another name for the set of output values for a function.

## What is the input of 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. A simple example is y = x2 (which you can also write f(x) = x2). In such cases, x is the input and y is the output.

## What is the definition of input in math?

A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output. function machine. close window. A function machine is a way of visualizing functions and their inputs and outputs.

## What is an input and output in science?

Systems always have inputs and outputs. An input is whatever you put into a system. An output is whatever comes out of the system. For example, a computer has inputs like electricity, the movements and clicks of your mouse, and the keys you type on a keyboard.

## What makes a relationship a function?

A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.

## How can you find the output number when you know the input number?

Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number ( -value) by 3 to find each output number ( -value). You can use a rule like this to find other values for this function, too.

## What is the function of a table?

A function is a rule that assigns a set of inputs to a set of outputs in such a way that each input has a unique output. A function table in math is a table that describes a function by displaying inputs and corresponding outputs in tabular form.

## What does F 2 mean?

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.

## What is a mathematical function?

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x2.

## What is the domain and what is the range?

Range. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

## Why does the vertical line test tell us whether the graph of a relation represents a function?

A function can only have one output, y, for each unique input, x. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.

## How is the vertical line test used?

Mathwords: Vertical Line Test. A test use to determine if a relation is a function. A relation is a function if there are no vertical lines that intersect the graph at more than one point.

## How do you know if a function is even or odd?

You may be asked to “determine algebraically” whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

## What is the function of odd?

about mathwords. website feedback. Odd Function. A function with a graph that is symmetric with respect to the origin. A function is odd if and only if f(–x) = –f(x).

## Which trigonometric functions are even and odd?

Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it’s important to know them. A function f is said to be an odd function if for any number x, f(–x) = –f(x).
