Let be the set of all vectors
b - 2d
5bd + d
b + 3d
d
where b and d are real.
Determine if is a vector space and check the correct answer below.
A.
is a vector space because it can be expressed as .
B.
is a vector space because it can be written as for some matrix .
C.
is not a vector space because it does not have a zero element.
D.
is not a vector space because it does not have additive closure.
