What is the rule for input 4 and output 13?
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.
What is the output for -2 if the function rule is 5x - 3?
5*(-2) - 3 = -10 - 3 = -13
What is the rule of an input of 2 and an output of17?
Supposing the input is n. Some of the infinitely many possible answers are: n + 15 2n + 13 3n + 11 4n + 9 and so on. or 1.5n + 14 2.5n + 12 or 19 - n 21 - 2n And then there are non-linear examples. The simpler ones are n2 + 13 n3 + 9 but there can be trigonometric or logarithmic or other functions.
