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 = 9
Whereas simply halving the output gives 9/2 = 4.5
So the question is based on false premises.
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
because there the same
Because doing so is equivalent to multiplying or dividing by x/x, which can be cancelled down to 1.
it is the same as multiplying by 0.4
1/2
10

No, taking ½ of a number is the same as dividing it by 2. Dividing a number by ½ is the same as multiplying it by 2.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
because of mathematical equivalence: it doesn't change the result
Multiplying by -1/3
1/2
The answer is positive.
If every input has an output. If two outputs are the same, they must have the same input.
