Question
For the matrix \( A \) below, find a nonzero vector in \( \text{Nul } A \), a nonzero vector in \( \text{Col } A \), and a nonzero vector in \( \text{Row } A \).

\[
A = 
\begin{bmatrix}
4 & -8 \\
-2 & 4 \\
-6 & 12 \\
-4 & 8 \\
\end{bmatrix}
\]

A nonzero column vector in \( \text{Nul } A \) is 
\[
\begin{bmatrix}
2 \\
1 \\
\end{bmatrix}
\]

A nonzero column vector in \( \text{Col } A \) is 
\[ \_\_\_ \]

**Explanation of Terms:**
- **Null Space (\( \text{Nul } A \))**: The set of all vectors that, when multiplied by matrix \( A \), result in the zero vector.
- **Column Space (\( \text{Col } A \))**: The span of the columns of \( A \).
- **Row Space**: The span of the rows of \( A \).

**Note:** The given answer for the nonzero vector in \( \text{Col } A \) is missing.
