Lets call the above set of points
.

The domain is between minimum and maximum of the x-coords points specified,

$\mathrm{min}(L;x)=0$

$\mathrm{max}(L;x)=7$

So domain is
$D_L=[\mathrm{min}(L;x),\mathrm{max}(L;x)]=[0,7]$ .

The range is the same story but you look at y values,

$\mathrm{min}(L;y)=-8$

$\mathrm{max}(L;y)=8$

So range is
$R_L=[\mathrm{min}(L;y),\mathrm{max}(L;y)]=[-8,8]$ .

Hope this helps :)
