If the domain of the function 6x2 - 3y = 9 is {-1, 2, 5}, then what is the corresponding range?

6x^(2)-3y=9
6x^(2)=3y+9...
(6x^(2))/(6)=(3y)/(6)+(9)/(6)...
x^(2)=(3y)/(6)+(9)/(6)...
x^(2)=(y+3)/(2)...
x=\~((y+3)/(2))...
x=\(~(y+3))/(~(2))...
x=\(~(y+3))/(~(2))*(~(2))/(~(2))...
x=\(~(2(y+3)))/(2)...
x=(~(2(y+3)))/(2).. [ .
x=-(~(2(y+3)))/(2)...
x=(~(2(y+3)))/(2),-(~(2(y+3)))/(2)..
(2(y+3)) =-3_[-3, I )...
The Range: is y>=-3_[-3, I )
Note: I is the sign for the infinte sign ]
