1.1) Sea \( F: \mathbb{R}^{3} \rightarrow \mathbb{R}^{2} \) la transformación lineal cuya matriz asociada es: \( M(F)_{B E}=\left(\begin{array}{ccc}-1 & 1 & 0 \\ 2 & 0 & k\end{array}\right) \) siendo \( B=\{(0,1,0),(-1,1,0),(0,0,2)\} \) y \( E \) : base canónica de \( \mathbb{R}^{2} \). 1. Probar que \( F \) es sobreyectiva \( \forall k \in \mathbb{R} \). 2. Obtener el valor de \( k \) para que \( N u(F)=\left\{(x, y, z) \in \mathbb{R}^{3} / 2 x+y=0 \wedge 3 y-z=0\right\} \).
