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

Lösung

leitkurve

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

Lösung

y = - 3

Schritte zur Lösung

Rewrite

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

in the standard form

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

(h, k) = (- 4, - 1), 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

(- 4, - 1)

y-coordinate

y = - 1 - p

y = - 1 - 2

Fasse zusammen

y = - 3
