Suppose that z = x'y*, where bothx and y are changing with time. At a certain instant when x = 1 and y = 2, x is decreasing at the rate of 2 units/s, and y is increasing at the rate of 3 units/s. How fast is z changing at this instant? Is z increasing or decreasing? Enter the exact answer. Rate of change of z = i units/s z is ej increasing decreasing Media
