The following is an example of the types of problems I am trying to do but am completely stuck. I am hoping somebody will answer this one so I will be able to complete the rest of my homework. Thank you for your help.

Compute a basis for the row space of A, the column space of A, the row space of A^T, and the column space of A^T. Write a short description giving the relationships among these bases.

A= $\displaystyle \begin{pmatrix}2 & -3 & -7 & 11\\3 & -1 & -7 & 13\\1 & 2 & 0 & 2\end{pmatrix}$
