Whakaoti i te y^2=4-x

$$y ^ { 2 } = 4 - x$$

Whakaoti mō x

$$x=4-y^{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4-x=y^{2}$$

Tangohia te 4 mai i ngā taha e rua.

$$-x=y^{2}-4$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-x}{-1}=\frac{y^{2}-4}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$x=\frac{y^{2}-4}{-1}$$

Whakawehe y^{2}-4 ki te -1.

$$x=4-y^{2}$$

Whakaoti mō y (complex solution)

$$y=-\sqrt{4-x}$$

$$y=\sqrt{4-x}$$

Whakaoti mō y

$$y=\sqrt{4-x}$$

$$y=-\sqrt{4-x}\text{, }x\leq 4$$
