What would be the local minimum for the function represented as f(x,y) = x2 +ay+y2 -3x ? Pick one.
A) (1,1)
B) (2,-1)
C) (-1,1)
D) (2,2)
E) (3,2)
f(x,y) = x2 + ay + y2 - 3x   = 4 - a + 1 - 6   = -a-1   So the above value will be the minimum if u check for all other options also. therefore, the answer is (2,-1)   ANSWER:(2,-1)
