Whakaoti i te y_{0}=4*(-1/8)^2+1/8-3

$$y _ { 0 } = 4 \cdot ( \frac { - 1 } { 8 } ) ^ { 2 } + \frac { 1 } { 8 } - 3$$

Whakaoti mō y_0

$$y_{0} = -\frac{45}{16} = -2\frac{13}{16} = -2.8125$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Ka taea te hautanga \frac{-1}{8} te tuhi anō ko -\frac{1}{8} mā te tango i te tohu tōraro.

$$y_{0}=4\left(-\frac{1}{8}\right)^{2}+\frac{1}{8}-3$$

Tātaihia te -\frac{1}{8} mā te pū o 2, kia riro ko \frac{1}{64}.

$$y_{0}=4\times \frac{1}{64}+\frac{1}{8}-3$$

Whakareatia te 4 ki te \frac{1}{64}, ka \frac{1}{16}.

$$y_{0}=\frac{1}{16}+\frac{1}{8}-3$$

Tāpirihia te \frac{1}{16} ki te \frac{1}{8}, ka \frac{3}{16}.

$$y_{0}=\frac{3}{16}-3$$

Tangohia te 3 i te \frac{3}{16}, ka -\frac{45}{16}.

$$y_{0}=-\frac{45}{16}$$

Tautapa y_0

$$y_{0}≔-\frac{45}{16}$$
