Given that the points $A(-2, y\_1)$, $B(0, y\_2)$ and $C(3, y\_3)$ are all on the graph of $f(x)=-2x^{2}+4x+m$, then the relationship among $y\_1$, $y\_2$ and $y\_3$ is:

The parabola opens down with axis of symmetry $x=1$. Therefore, point $B$ is closer the axis of symmetry than point $C$, and point $C$ is closer the axis of symmetry than point $A$
