1 Compute Fx for the following vectors x: \text { (a) } \mathbf{x}=\left[\begin{array}{l} 1 \\ 1 \end{array}\right] \text { (b) } \mathbf{x}=\left[\begin{array}{r} 1 \\ -1 \end{array}\right] \text { (c) }

\mathbf{x}=\left[\begin{array}{l} -1 \\ -1 \end{array}\right] \text { (d) } \mathbf{x}=\left[\begin{array}{r} -1 \\ 1 \end{array}\right]
