5. Check whether the following functions satisfy the following properties: i) Increasing in both inputs. ii) Diminishing marginal products. iii) Constant returns to scale. iii) Complementarity between capital and labor. a) Y = KO. NO.7 b) Y = 2K +3N c) Y = K03 NO.7 d) Y = 2N+2 Use the fact that given a function of the form Y = KN marginal products are given by MPN = BK NB-1, MPK = aK-'NB
