5. a) Let S be a convex subset of R" and {: SR. Define what is understood by saying that is convex and what is understood by saying that is concave. (b) Let A be an nx n matrix. Define what is understood by saying that A is positive semidefinite and what is understood by saving that A is negative semidefinite, (c) Let (KL) = A[5K+ (1 - 1) - fr for K. L > 0. A > Op bé and 050 31. Determine (with proof) the values of p for which is concave and the values of p for which is convex, 20 marks
