WebI think this way is easier and more general: To find the column space of a matrix, you don't need to use an augmented matrix. Just use column reduction, which will get you to: $$\left[ \begin{array}{ccc} 1&1&-3\\ 0&2&1\\ 1&-1&-4 \end{array} \right] \sim \left[ … WebDetermine if wis in Col (A).

http://math.oit.edu/~watermang/math_341/341_ch8/F13_341_book_sec_8-4.pdf WebTo determine if w is in Col (A), we need to check if Ax-w is consistent. This is because the vector w is a linear combination of the columns of A, and as such, Ax-w is a consistent system. Therefore, w is in Col (A). To determine if w is in Nul (A), we need to check if Ax =w is an inconsistent system.
