Match each Cobb-Douglas production function (a)-(c) with a graph in the figure below and a statement (D)-(G).

(a) $F(L,K) = L^{0.125}\,K^{0.375}$
(b) $F(L,K) = L^{0.25}\,K^{0.75}$
(c) $F(L,K) = L^{0.825}\,K^{0.625}$

(D) doubling each input almost triples output : ? a b c
(E) doubling each input doubles output : ? a b c
(G) quadrupling each input doubles output : ? a b c

(1): graph (1) : ? a b c
(2): graph (2) : ? a b c
(3): graph (3) : ? a b c
