The set V = R³ with the operations of vector addition and scalar multiplication defined as (x1, 91, 21) + (x2, 92, 22) = (x2, y2, 22) and c(x1, y1, 21) = (cx1, cy₁, cz₁) is a) a vector space. b) not closed under scalar multiplication and hence not a vector space. c) not commutative and hence not a vector space. d) none of the above.
