1. The problem statement, all variables and given/known data For each s [tex]\in[/tex]R determine whether the vector y is in the subspace of R^4 spanned by the columns of A where y= 6 7 1 s and A = 1 3 2 -1 -1 1 3 8 1 4 9 3 2. Relevant equations 3. The attempt at a solution Can i do this by making an augmented matrix from A and y and then reducing it, then i can see what value of s is required? i will attemp this and update with what i get soon.
