## What graph shows a function where F 2 )= 4?

Any graph which passes through the point (2,4) will be the required graph. f(x)=x^2 is a function which gives f(2)=4 and its geometrical representation is a parabola.

## Which of the graph shows a function?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

## What are the examples of functions?

In mathematics, a function can be defined as a rule that relates every element in one set, called the domain, to exactly one element in another set, called the range. For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value.

## How can you identify a function?

You can use the vertical line test on a graph to determine whether a relation is a function. If it is impossible to draw a vertical line that intersects the graph more than once, then each x-value is paired with exactly one y-value. So, the relation is a function.

## What are the types of function graphs?

Different types of graphs depend on the type of function that is graphed. The eight most commonly used graphs are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal.

## What are the 4 types of functions?

The types of functions can be broadly classified into four types. Based on Element: One to one Function, many to one function, onto function, one to one and onto function, into function.

## What is a function in math graph?

When the graph of a relation between x and y is plotted in the x-y plane, the relation is a function if a vertical line always passes through only one point of the graphed curve; that is, there would be only one point f(x) corresponding to each x, which is the definition of a function.

## What is function give two examples?

Some Examples of Functions

x2 (squaring) is a function. x3+1 is also a function. Sine, Cosine and Tangent are functions used in trigonometry. and there are lots more!

## What are four examples of functions?

we could define a function where the domain X is again the set of people but the codomain is a set of number. For example , let the codomain Y be the set of whole numbers and define the function c so that for any person x , the function output c(x) is the number of children of the person x.

## What are the two main types of functions?

2. What are the two main types of functions? Explanation: Built-in functions and user defined ones.

## What is the two function of computer?

Answer: The main functions of computer is input, processing, output & storing the data.

## Which keyword is used for function?

the def keyword
Explanation: Functions are defined using the def keyword.

## Where is function defined in Python?

Here are simple rules to define a function in Python. Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ). … You can also define parameters inside these parentheses.
