Since an absolute value is never negative, if M M can be zero then zero is the minimum. I believe you can find the value of x x for which M M is zero. Now we need to find out the maximum. and solving for x and y - you obtain. x = 4(3a2 − a + 3b2) 9a2 + 9b2 − 1. and. y = 4b 9a2 + 9b2 − 1. Therefore, if you compute. f(4(3a2 − a + 3b2) 9a2 + 9b2 − 1 + i 4b 9a2 + 9b2 − 1), the answer is a + bi (as you can verify). This shows that all complex numbers a + bi are in the range - except those for which this formula is not ... If brain fog or lack of concentration bothers you daily, it might be due to your diet.
