Given vectors $\overset{⇀}{a} =(\cos x, \sin x)$ and $\overset{⇀}{b} =(3, -\sqrt{3})$, where $x \in [0, \pi]$.

(1) Find the value of $x$ if $\overset{⇀}{a}$ is parallel to $\overset{⇀}{b}$.

(2) Let $f(x) = \overset{⇀}{a} \cdot \overset{⇀}{b}$. Find the maximum and minimum values of $f(x)$ and the corresponding values of $x$.
