Answer the following questions. You do not need to justify your answers. (a) Let X be the set of all 3×3 matrices whose diagonal entries are all 0. With the usual matrix addition and scalar multiplication, is X a vector space? (b) Let Y be the set of all 3 × 3 matrices whose diagonal entries add up to 0. With the usual matrix addition and scalar multiplication, is Y a vector space? (c) Let Z be the set of all polynomials of degree exactly 5. Is Z a vector space?
