6. Determine whether or not V spans R and choose a correct justification: 2, vs) , where vi = ,V321 (A) V spans R2 because its echelon form contains a leading entry in every column. (B) V spans R2 because r vi - b is consistent for all b e R? (C) V does not span R2, because vs is an scalar multiple of v2. (D) V does not span R2, because a set of three vectors can only span...
