Question
Let W be the set of all vectors of the form shown on the right, where a and b represent arbitrary real numbers. Find a
set S of vectors that spans W, or give an example or an explanation showing why W is not a vector space.
- a+1
a - 4b
2b +a
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The set W is a vector space and a spanning set is S=-
(Use a comma to separate vectors as needed.)
B. The set W is not a vector space because the zero vector is not in W.
O C. The set W is not a vector space because not all vectors u, v, and w in W have the property that u +v =v+u and (u + v) + w= u+ (v + w).
O D. The set W is not a vector space because not all vectors u in W have the property 1u = u.
