function
A function is a rule which assigns exactly one output f(x) to every input x.
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.
The rule appears to be a linear relationship between the input and output values. When the input increases by 4 (from 1 to 5), the output decreases by 4 (from 5 to 1). Similarly, when the input increases by another 4 (from 5 to 9), the output decreases by 4 again (from 1 to -3). Therefore, the rule seems to be that for every increase of 4 in the input, the output decreases by 4.
It is a bijective function.
The amount of gas you put in a car is the input. The input is expended to produce a benefit in the form of an output which in this case is the number of miles traveled with the gas you put in.
There are lots of possible rules.The simplest is:output = input + 13However all the following will also work:output = 33 - inputoutput = 2.3 x inputoutput = 230 / inputoutput = 73 - 5 x inputoutput = 2 x input + 3The above is only a small number of the many, many, many rules which meet the criteria of input of 10 giving an output of 23.
A Function
The relationship is called a surjection or a surjective function.
Input = Keyboard Input = scanner Output = printer Storage Devices = Hard Drive Storage Devices = Thumb Drive
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.
There need not be any relationship.
For a relationship to be considered a function, each input value must correspond to exactly one output value. This means that each input cannot have multiple outputs.
what do you mean by input/ouput units?
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
