Solution:
0≤x2+2y≤4
For y=−3,x={3,−3}
For y=−2,x={−2,2}
For y=−1,x={−2,2}
For y=0,x={−2,−1,0,1,2}
For y=1,x={−1,0,1}
For y=2,x={0}
‌R={(3,−3),(−3,−3),(−2,−2),(2,−2),(−2,−1),
‌(2,−1),(−2,0),(−1,0),(0,0),(1,0),(2,0),(−1,1),
‌(0,1),(1,1),(0,2)}
‌I=15
We need to add (−1,−1),(2,2),(3,3) to make it reflexive
m=3⇒I+m=18
