Consider the following utility functions. G(x,y) = -1 / [ min(6x,2y) +1] H ( xy) = min (6x, 6y) L(x,y) = min(6x,2y) - 10000000000 U ( x,y ) = min ( 3x, y) W( x,y) = min (6x, y) + 2 Z( x,y) = min (x,2y) Which of the above functions, if any, is homogeneous of degree 2? Select one or more: O a. U Ob. L c. H O d. G O e. None. Of. W O g. Z
