leitkurve x^2-4x-8y+2=0

Lösung

leitkurve

x^{2} - 4 x - 8 y + 2 = 0

Lösung

y = - \frac{9}{4}

Schritte zur Lösung

Rewrite

x^{2} - 4 x - 8 y + 2 = 0

in the standard form

4 \cdot 2 (y - (- \frac{1}{4})) = (x - 2)^{2}

(h, k) = (2, - \frac{1}{4}), p = 2

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(2, - \frac{1}{4})

y-coordinate

y = - \frac{1}{4} - p

y = - \frac{1}{4} - 2

Fasse zusammen

y = - \frac{9}{4}
