List your group members full names and describe the contribution of each group member.   Example: Agatha performed background research on malpractice, Hubert put together the slides, etc.

List 5 important facts from the syllabus and/or course schedule after reading the attached document. 

Consider $$A = \begin{bmatrix}&3 & 5 & -2 & 1 &0 \\&1 & -1 & 0 & 3 &0 \\&-6 & -10 & 4 & -2 &0 \\&2 & -2 & 0 & 5 & 2\\\end{bmatrix}$$   a) Find the nullspace of A (Nul(A) = span{…}).   b) Find a basis for the column space of A.   c) Is A invertible? Justify your answer using part b).  

Augment the following matrix with the identity then find its inverse. $$A = \begin{bmatrix}&3 &6 & 3 \\&1 & 2 & 2 \\& -2 & 2 & 8\end{bmatrix}$$

Let $$A = \begin{bmatrix}&1 &2 & 1 & 0 \\&3 & 3 & 2 & 0 \\&23 & 64 & 19 & 5 \\&5 & 4 & -1 & 0\end{bmatrix}$$   a) Use the row reduction algorithm to find det(A). b) Use the cofactor method to find the det(A). Your answers from parts a) and b) should agree
