Whakaoti mō y
y=7-x^{2}
Whakaoti mō x (complex solution)
x=-\sqrt{7-y}
x=\sqrt{7-y}
Whakaoti mō x
x=\sqrt{7-y}
x=-\sqrt{7-y}\text{, }y\leq 7
Graph
Tohaina
Kua tāruatia ki te papatopenga
1y-7=-x^{2}
Tangohia te x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
1y=-x^{2}+7
Me tāpiri te 7 ki ngā taha e rua.
y=7-x^{2}
Whakaraupapatia anō ngā kīanga tau.
