4. Is the state space representation $A = \begin{bmatrix} -1 & 0 \\ 0 & 2 \end{bmatrix}$, $B = \begin{bmatrix} 1 \\ 0 \end{bmatrix}$, $C = \begin{bmatrix} 0 & 1 \end{bmatrix}$, $D = \begin{bmatrix} 0 \end{bmatrix}$ observables? (a) No, it is not, because the state $x_1(t)$ is not observable. (b) Yes, because its observability matrix is full rank. (c) No, it is not, because the state $x_2(t)$ is not observable. (d) No, it is not, because the eigenvalue corresponding to the dynamics of the state $x_2(t)$ has $Re(\lambda) > 0$. (e) None of the above.

Consider the function $f(x) = \sqrt{1 - x} + 9$ for the domain $(-\infty, 1]$. Find $f^{-1}(x)$, where $f^{-1}$ is the inverse of $f$. Also state the domain of $f^{-1}$ in interval notation.
