Column Space and Linear Combinations Question
I am stuck on how to work out this question.
1) In each case determine whether b is in the column space of A, and if so, express b as a linear combination of the column vectors A.
My answer so far to (b):
Is someone able to let me know if this column space is correct?
My main question: If so, how am I supposed to find out if b is in the column space?
