Question: Consider the function \"3.9) : (4 - $2 y?)ez+y- (1) Find the maximal and minimal values of function f(z.y under the constraint 1'2 + y2 = 1. Hint: Under the constraint 1'2 + y? = 1, we have y : i 1 .132, 1 5 :1: g 1, and therefore H3. :9) = 90'?) = 38m" \"I\" with - 1 g m g 1. It sniees to nd maximal and minimal values of 9(1) on the closed interval :1: E [1,1]. 0n the closed interval 1* e [-1.1], one needs to compare the function values at all the stationary points of 9(3) on [1, 1] and the endpoints :5 = 5:1
