In part A, it is given that | x | = 8. Therefore, the two integers 8 and -8 would be solutions because the absolute value sign renders all negative numbers to be positive.
In this picture provided, x appears to be less than three. Because it is in absolute value form, any number substituted for x is positive. This means that the numbers 3, 2, 1, and 0 are all answers to part B.
In the second graph of part B, x is greater than or equal to 3. This would mean any number that is 3 or more would be a solution.
