## Whats 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.

### When given a function what is the input rule?

You can also write the rule for a function rule as an equation. Here is an example. The equation y=x/3+1 is a function. The input is the x-value and the corresponding y-value is the output.

#### What is the function rule?

A function rule is the relationship between the dependent and independent variables in the form of an equation. The function rule of a specific function, explains how to determine the value of the dependent variable say y, in terms of the independent variable say x.

**What is the function rule calculator?**

A Function Calculator is a free online tool that displays the graph of the given function. BYJU’S online function calculator tool makes the calculations faster, and it displays the graph of the function by calculating the x and y-intercept values, slope values in a fraction of seconds.

**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 the output value of a function?

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input.

### What is the input to the function when the output is 5?

So, yes it is. In this case, each term in the input was multiplied by five to get the term in the output….Writing Function Rules for Input-Output Tables.

Input | Output |
---|---|

5 | 8 |

#### How do you find a function rule from a table?

To find if the table follows a function rule, check to see if the values follow the linear form y=ax+b y = a x + b . Build a set of equations from the table such that q(x)=ax+b q ( x ) = a x + b . Calculate the values of a a and b b . Solve for a a in 1=a+b 1 = a + b .
