Question

We are looking for a solution of this function :

f ∶ R2 → R
(x, y) → x2+ y2− 4x + 4

with constraint  : 

min f(x,y) / (x,y) in K2 --> K2={(x,y) in R2 ; 2x-y2 <= 1 & x >= 0}

 

a) show that if (x',y') is a local minimum :

(x',y') in {(1,-1),(1,1),(0.5,0)}

b) calculate f(1, 1), f(1, −1) and f(0.5, 0).
