Question

What rule changes the input to output numbers?

Answer 1

The correct answer is B ( 2x - 8 )

Plug in each individual answer to where x goes and the solve.


Check:
2(1)-8=-6
2(2)-8=-4
2(3)-8=-2
2(4)-8=0

Answer 2

Each pair of numbers in the table is related by the same function rule. That rule is: multiple  each input number value by 3 to find each output number value. You can use a rule like this to find other values for this function, too
