Given:
y < 3x² + 3x - 6
Find inequality
(a) For (0,3)
3<3(0)²+3(0)-6
3<0+0-6
3<-6
The inequality is not satisfied.
(b) For (-1,-1)
-1<3(-1)²+3×-1-6
-1<3-3-6
-1<-6
The inequality is not satisfied.
(c) For (-1,2)
2<3(-1)²+3×-1-6
2<3-3-6
2<-6
The inequality is not satisfied.
(d) For (1, -2)
-2<3(1)²+3×1-6
-2<3+3-6
-2<0
The inequality is satisfied.
The correct option is "d"
Hence the answer is (1,-2)
