2. Determine whether the following sets with the corresponding vector addi-
tion and scalar multiplication form vector spaces.
a) Let V = {(a₁, a2): a1, a2 € R}. For (a₁, a2), (b₁,b₂) € V and c € R,
define:
(a₁, a2)+(b₁,b2) = (a₁ +2b₁, a2 + 3b2) and c(a₁, a2) = (ca₁,ca2)
b) Let V = {(a1, a2): a1, a2 € R}. For (a1, a2) € V and c € R, define:
c(a1, a2) = (ca₁,0)
