To find the values for output (y) for different input (x) using the given function rule, we substitute the values of x into the function rule and solve for y.

Given that the function rule is 2 less than 4 times x, we can write it as:
y = 4x - 2

Now, let's substitute the given values of x into the function rule to find the corresponding values of y:

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

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

For x = 1:
y = 4(1) - 2
y = 4 - 2
y = 2

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

Hence, the completed table would look like this:

input(x) output(y)
-1 -6
0 -2
1 2
2 6
