Whakaoti i te x^2=-2(y-4.5)

$${ x }^{ 2 } =-2(y-4.5)$$

Whakaoti mō y

$$y=\frac{9-x^{2}}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te y-4.5.

$$x^{2}=-2y+9$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$-2y+9=x^{2}$$

Tangohia te 9 mai i ngā taha e rua.

$$-2y=x^{2}-9$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2y}{-2}=\frac{x^{2}-9}{-2}$$

Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.

$$y=\frac{x^{2}-9}{-2}$$

Whakawehe x^{2}-9 ki te -2.

$$y=\frac{9-x^{2}}{2}$$

Whakaoti mō x (complex solution)

$$x=-\sqrt{9-2y}$$

$$x=\sqrt{9-2y}$$

Whakaoti mō x

$$x=\sqrt{9-2y}$$

$$x=-\sqrt{9-2y}\text{, }y\leq \frac{9}{2}$$
