Prove the following properties of unit costs (a) MC(y) AC(y) SAC(y) increasing minimal decreasing. (b) lim AC(y) SMC(0) if F = 0 if F >0. y-0 y-0 (c) lim AVC(y) = MC(O) (d) lim AC(y) = lim AVC(y). (e) Same as (1) replacing AC by AVC. Y-00 400 Prove the following properties of unit costs (a) MC(y) AC(y) SAC(y) increasing minimal decreasing.
