Q$\mathrm{.}1$ The system is described by the equation where the values of a$,$ b$,$ and c are $1,7,$ and $9$ respectively. $($i$)$ Determine the transient response of the system for initial conditions x$($t$=0)=1,$ and x $($t$=0)=0.($ii$)$ Is the transient response oscillatory? If not, what will be the critical value of b $($keeping a and c constant$)$ at which the system exhibits an oscillatory response?
