To find the approximate change in z we only need to compare the third hexadecimal number (from left to right) in each point. In the first case, it changes from 22be to 22bf, which represents an increment of one unit. In the second case, it changes from 22c1 to 49d2, which represents an increment of (49d2-22c1) = 1027 units. Therefore, the total change in z is approximately 1+1027 = 1028 units or 0.004 in decimal approximation. Thus, the correct answer is D) 0.004.
