### Determine Basis and Linear Independence

Determine if the set of vectors shown to the right is a basis for \(\mathbb{R}^3\). If the set of vectors is not a basis, determine whether it is linearly independent and whether the set spans \(\mathbb{R}^3\).

\[
\left\{
\begin{bmatrix} 
3 \\ 
-1 \\ 
1 
\end{bmatrix},
\begin{bmatrix} 
2 \\ 
-4 \\ 
2 
\end{bmatrix},
\begin{bmatrix} 
-9 \\ 
6 \\ 
3 
\end{bmatrix}
\right\}
\]

### Multiple Choice Question

Which of the following describe the set? Select all that apply.

- [ ] A. The set is a basis for \(\mathbb{R}^3\).
- [ ] B. The set is linearly independent.
- [ ] C. The set spans \(\mathbb{R}^3\).
- [ ] D. None of the above

---

To solve the question, analyze if the given vectors are linearly independent and if they span the vector space \(\mathbb{R}^3\). A set of three vectors is a basis for \(\mathbb{R}^3\) if it is linearly independent and spans \(\mathbb{R}^3\).
