Question

If the column space of a 3x3 matrix consists of all vectors b=[b1, b2, b3] such that
b1+ b2= 3b3 then,
one of the following set of the vectors forms a basis for the left null space of that matrix:

Answer 1

Answer:

Already b=(b1, b2, b3) has given

Step-by-step explanation:

In last thereis b3 so that when b1 +b2 = 3b3, if there is already b3 then 3b comes and it will be added to it so it becomes 3b3
