Given the matrix (included in image attachment)


Find a basis for each of the subspaces R(AT), N(A), R(A), N(AT)

The image displays a matrix labeled as "A". This matrix is a 2x3 matrix, which means it has two rows and three columns. The elements of the matrix are arranged as follows:

- First row: 1, 2, 4
- Second row: 2, 5, 8

The matrix can be represented as:

\[
A = \begin{bmatrix}
1 & 2 & 4 \\
2 & 5 & 8
\end{bmatrix}
\]

Matrices like this are commonly used in various fields such as mathematics, physics, economics, and engineering for solving systems of equations, transforming geometric coordinates, and more. Understanding how to manipulate and use matrices is a fundamental skill in linear algebra.
