can you help me solve these questions

Queson 3 Illustrate the following: 3} Suppose the utility that one receives from consuming Goods A and B can be either positive or negative, represented by a vector u(uA, 1:3). 1When the consumption is enjoyable, the utility is positive and when the consumption becomes a burden, the utility becomes negative. Consider 2 utility combinations 111 and uz , where HI = (4,1) and u: = (2,3). Illustrate the difference between these two utility levels in a 2-dimensional setting. [5 Marks] b) Expand the setting in Part 1] to a 3-dimensional case, i.e. there now exist 3 2 i] l] commodities A, B and C. Given 3 utility levels 111 2 [ll], H: = 31 and n3 2 [D], U D 2 depict the vector 2111 + u: + 2113. [5 Marks]
