Subspace or not?

  1. Oct 27, 2012 #1
    Hi. I'm trying to check if my approach is right.

    The problem is attached.

    I need to check these:
    1) 0 vector is in S
    2) if U and V are in S then U+V is in S
    3) if V is in S, then cV where c is a scalar is in S

    The 1st condition is not satisfied right?
    Since A*[0 0]^t=[0 0]^t≠[1 2]^t?
