Anything you like - it depends on the function that relates the output to the input.
If by 'rule' you mean 'function' then there are an infinite number of possible answers. However, here are some examples. (Let input be x and output y.) Linear Functions y = x + 6 y = 3x + 10 Polynomials y = 3x2 - x - 10 y = x4 + 2x3 + 3x2 - 2x - 12 Exponentials y = 0.5x
Input/output table, description in words, Equation, or some type of graph
y = 8 - 2*x
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7
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.
Multiply by 5 and add 20 (or equivalently, add 4 and then multiply by 5)
There are an infinite possible answer. Among the simpler ones is: Output = Input - 2
Anything you like - it depends on the function that relates the output to the input.
There are infinitely many possible answers. Rule 1: Add 9 to Input Rule 2: Add 5 to 2*Input Rule 3: Add 1 to 3*Input Rule 4: Subtract -3 from 4*Input or, moving away from whole numbers, Add 3.8 to 2.3 times Input.
A table in which you put in a number and out comes another number. Usually more than one groups of numbers. And almost ALWAYS follows a rule such as: Input x3=Output or Input -23= Output Input | Output 2 | 4 10 | 20 16 | 32 In this table you can see that the rule is Input x2 = Output Hope This helped!
The simplest of infinitely many possible solutions, is y = x2
The rule that determines the output number based on the input number is known as a function. For example take the function: f(x) = x+1. F is the name of our function, x is the input number, and f(x) is our output number. So if our input number is 3, our function or "rule" says to add one to it. Therefore, f(x), known as the output number, would be 4 since 3+1 = 4.
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.
All inputs hae to be low i.e 0.
