Find the transfer function, $G(s)=x_1\frac{s}{F}(s),$ for the following translational mechanical system.

$\frac{x_1(s)}{F(s)}=\frac{s^2+14}{3s^4+22s^3+38s^2+4s+15}$

$\frac{x_1(s)}{F(s)}=\frac{3s^2+10s+2}{4s^4+15s^3+32s^2+13s+40}$

$\frac{x_1(s)}{F(s)}=\frac{3s+5}{2s^4+17s^3+44s^2+45s+20}$

$\frac{x_1(s)}{F(s)}=\frac{s+10}{s^4+7s^3+4s^2+5s+2}$
