In the given question, we have to select that table, which follows the rule that
output is the difference of input and 6 .
Let's check the second table .
The first input is -7.
And difference of -7 and 6 is -13, and it is given that -13 is the output. So its true .
The second input is -2. And difference of -2 and 6 is -8, which is the given output. So its true .
The last input is 6 and difference of 6 and 6 is 0 which is the given output. So its true .
Therefore the correct option is the second table .
