an 6 Let a = [], -), and 2 = [1] The goal of this question is to give and justify a drawing of the set of convex linear combinations of a, b, and 2. This requires an understanding of the previous question, (a) Let d = Write d as a convex linear combi- nation of ã and B. (b) Let ? = 10). Write ? as a convex linear combi- nation of 7 and ä. (c) Substituting the answer to (6a) into the answer to part (6b), write ? as a convex linear combi- nation of a, b, and c. (d) Draw and label a, b, c, d, and ? on the same grid. (e) Draw the set of convex linear combinations of ?, b, and C. Justify your answer.
