**Question 1: POOLLLINALG4 6.e.012**

Test the set of functions for linear independence in \( \mathbb{F} \). If it is linearly dependent, express one of the functions as a linear combination of the others. (If the set is linearly independent, enter INDEPENDENT. If the set is linearly dependent, enter your answer as an equation using the variables \( f \) and \( g \) as they relate to the question.)

Functions: 
- \( f(t) = e^t \)
- \( g(t) = e^{-t} \)

---

**Question 2: POOLLLINALG4 6.e.018**

Determine whether the set \( B \) is a basis for the vector space \( V \).

\[ V = M_{2 \times 2} \]

\[ B = \left\{ \begin{bmatrix} 1 & 0 \\ 1 & 0 \end{bmatrix}, \begin{bmatrix} 0 & 1 \\ 0 & 1 \end{bmatrix}, \begin{bmatrix} -1 & -1 \\ 1 & 1 \end{bmatrix} \right\} \]

Options:
- \( B \) is a basis for \( V \).
- \( B \) is not a basis for \( V \).
