Linear Algebra

============

Question 9 is about the \"subspace requirements\": I + y and ex (and then all linear combinations on: + dy) stay in the subspace. 9 One requirement can be met while the other fails. Show this by nding (a) A set of vectors in R2 for which I + y stays in the set but %x may be outside. (1:) A set of vectors in R1 (other than two quarter-planes) for which every 0.1: stays in the set but .1: + y may be outside
