Whakaoti mō y
y=\frac{9-x^{2}}{2}
Whakaoti mō x (complex solution)
x=-\sqrt{9-2y}
x=\sqrt{9-2y}
Whakaoti mō x
x=\sqrt{9-2y}
x=-\sqrt{9-2y}\text{, }y\leq \frac{9}{2}
Graph
Tohaina
Kua tāruatia ki te papatopenga
-2y=x^{2}-9
Tangohia te 9 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{x^{2}-9}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{x^{2}-9}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{9-x^{2}}{2}
Whakawehe x^{2}-9 ki te -2.
