Whakaoti i te y=4-0*x-0.5*9.8066*x^2

$$y=4-0 \times x-0.5 \times 9.8066 \times { x }^{ 2 }$$

Whakaoti mō y

$$y=-\frac{49033x^{2}}{10000}+4$$

Ngā Upane Otinga

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$y=4-0-0.5\times 9.8066x^{2}$$

Tangohia te 0 i te 4, ka 4.

$$y=4-0.5\times 9.8066x^{2}$$

Whakareatia te 0.5 ki te 9.8066, ka 4.9033.

$$y=4-4.9033x^{2}$$

Whakaoti mō x (complex solution)

$$x=-\sqrt{\frac{40000-10000y}{49033}}$$

$$x=\sqrt{\frac{40000-10000y}{49033}}$$

Whakaoti mō x

$$x=\frac{\sqrt{\frac{160000-40000y}{49033}}}{2}$$

$$x=-\frac{\sqrt{\frac{160000-40000y}{49033}}}{2}\text{, }y\leq 4$$
