The problem states that the output $y$ is "2 less than 4 times $x$." This can be written as the function:

$y = 4x - 2$

Using this function, let's calculate $y$ for each input $x$ in the table:

1. For $x = -1$: $y = 4(-1) - 2 = -4 - 2 = -6$

2. For $x = 0$: $y = 4(0) - 2 = 0 - 2 = -2$

3. For $x = 1$: $y = 4(1) - 2 = 4 - 2 = 2$

4. For $x = 2$: $y = 4(2) - 2 = 8 - 2 = 6$

Now, we can complete the table:
