Plug in x values and obtain y values using the equation.
{{{x=-3}}}, {{{y=x^2+6x+8=9-18+8=-1)}}}
.
{{{x=-2}}}, {{{y=4-12+8=0}}}
{{{x=-4}}}, {{{y=0}}} by symmetry since {{{x=-3}}} is the line of symmetry.
.
.
{{{x=-1}}},{{{y=1-6+8=3}}}
{{{x=-5}}},{{{y=3}}} by symmetry.
.
.

{{{x=0}}},{{{y=0+0+8=8}}}
{{{x=-6}}}, {{{y=8}}} by symmetry.
