 {{{x=-2}}}, {{{y(-2)=(-2)^2-2=4-2=2}}}
 {{{x=-1}}}, {{{y(-1)=(-1)^2-2=1-2=-1}}}
 {{{x=0}}}, {{{y(0)=(0)^2-2=0-2=-2}}}
 {{{x=1}}}, {{{y(1)=(1)^2-2=1-2=-1}}}
 {{{x=2}}}, {{{y(2)=(2)^2-2=4-2=2}}}
 {{{x=3}}}, {{{y(3)=(3)^2-2=9-2=7}}}
Graph those order pairs. 
{{{drawing( 300, 300, -5, 5, -5, 10,grid( 1 ),
circle( -3, 7, .2),
