WebClearly from (1), y is minimum when r.h.s. is minimum and r.h.s. is minimum when (x - 2/5)^2 is minimum, which a square quantity & the minimum value of a square quantity is always zero . So we must have, (x - 2/5)^2 = 0 ==> x = 2/5 and then from (1), y (min.) = 11/5 and it occurs at x = 2/5 . 1 Ragu Rajagopalan WebFinding the maximum and minimum values of a function also has practical significance, because we can use this method to solve optimization problems, such as maximizing profit, minimizing the amount of material used in manufacturing an aluminum can, or finding the maximum height a rocket can reach.
