What is the rule if the input is 17 18 _28 40 and the output numbers are 57 56 54_ 34

Your answer would be
A function is when one variable or term depends on another according to a rule. There is a special relationship between the two variables of the function where each value in the input applies to only one value in the output. These rules are called function rules, because they explain how the function operates.
