## Homework Statement

Give bases for row(A), col(A), and null (A). Also find bases for row(A) and col(A) using A

^{T}.

A=[1, 1, -3; 0, 2, 1; 1, -1, -4]

A

^{T}: [1, 0, 1; 1, 2, -1; -3, 1, -4]

## Homework Equations

## The Attempt at a Solution

For the first part I got the bases for row(A) to be [1, 0, -7/2] and [0, 1, 1/2].

For the col(A) I got [1;0;1] and [1;2;-1]

For the null(A) I got [7/2;1/2;1]

For the second part I got bases for row(A) to be [1, 0, 0] and [0, 1, 0]. For the basis for col(A) I got [1; 0; 1] and [0; 1; -1]

My teacher did not explain these concepts because he ran out of time, and it is due tomorrow. Please let me know where I messed up at, if anywhere. Thanks
