Schritte zur Lösung

Rewrite

y = - 0.0000848 x^{2} - 0.006005 x + 1.004

in the standard form

4 (- 2948.11320 \dots) (y - 0) = (x - (- \frac{0.006005}{0.0001696}))^{2}

(h, k) = (- \frac{0.006005}{0.0001696}, 0), p = - 2948.11320 \dots

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(- \frac{0.006005}{0.0001696}, 0)

along the y-axis

(- \frac{0.006005}{0.0001696}, 0 + p)

= (- \frac{0.006005}{0.0001696}, 0 + (- 2948.11320 \dots))

f oc i x^{2} + 16 y = 0

f oc i y = 4 x^{2} - 9

f oc i y = 160 x - 16 x^{2}

f oc i (1060 - x)^{2} + x^{2}

f oc i y^{2} + 8 x = 0
