Chapter 5, Problem 5.21P

The transfer function of a certain system is

$\frac{Y\left(s\right)}{F\left(s\right)}=\frac{6s+7}{s+3}$

Use two methods to obtain a state-variable model in standard form. For each model, relate the initial value of the state-variable to the given initial value $y\left(0\right)$ .
