You replace the relevant variable with -2, and do any calculation, lookup, etc., specified in the function definition.

What is the rule if the input is 6 and the output is 4?

The relationship between the input and output values is typically defined by a function. In this case, if the input is 6 and the output is 4, the function could be represented as f(x) = x - 2. This function subtracts 2 from the input value to get the output value.


What is the output value if the input value is 4?

Without knowing the specific function or equation being used, it is impossible to determine the output value if the input value is 4. In mathematics, the output value is dependent on the specific function or equation being evaluated. To find the output value when the input value is 4, you would need to know the function or equation being used and then substitute 4 in place of the input variable to calculate the output value.


Why is multiplying the Input by 2 is the same as dividing the Output by 2?

It is not. Suppose the function is "add 7".Then an input of 1 gives an output of 1+7 = 8.Double the input to 2 and the output is 2+7 = 9Whereas simply halving the output gives 9/2 = 4.5So the question is based on false premises.


Why when you press a it shows a?

It is a function. A function is the relationship between the input of an equation and its output wherefor each input has only one output (or answer). 2+2 will always equal 4, and pressing "a" in a word processor will always render and "a" on the screen.


What is the function rule for input -2 output 13?

There are many functions where if your input is -2 the output is 13. The simplest is probably just adding 15. You could also square -2 (to get 4) and then add 9.


What input/output ports are available on this model of television?

There are two input and output ports for Input 1 and 2 and Output 1 and 2.


What is the opposite of input?

Output. For example, if you input '2 + 2 =' in a calculator, the 4 that appears is the output.


How many input and output in half adder?

2 input and 1 output


Example of output is?

Input: "3+2" --- Output: "5" Input: "song.mp3" ---- Output: the music you listen to


What are different ways in representing function?

If you mean what are the various ways of representing a function? Then I'd suggest you ponder over the definition of a function at first. I think of functions as abstract entities that accept inputs and give a single output for every such input. Going off of this definition, various ways of representing a function are: 1) Explicit formula: This relates the output of a function to the input. i.e it tells you what exactly the function does to the input. eg. f(x) = x +2 tells you the function adds 2 to the input value. 2) The graph of a function: This gives you a good idea of how the function behaves in it's entire domain (the set of inputs for which the output is defined and real). 3) A table of inputs and outputs. 4) Verbal description of a function


Can a function assign the same output value to two different input values?

Yes. If you have a function that squares a number, the output will be the same for both positive and negative input of the number. e.g. 22 = (-2)2 Or if you use a boolean: If test > 0 return True test can be equal to 1 or 2 or anything else


What is the rule for an input output table?

An input/output table works like this:You input something, and through a function, it outputs something else!Say I Had a function that is: input+2If I were to input 5, It would output 7All an input/output table does is displays a couple examples of multiple inputs with their outputs! Put tables only operate on one function....Example:Function: Input x 5 + 3INPUTS - OUTPUTS----------------------1 - 82 - 133 - 186 - 3310 - 53
