leitkurve x^2+4x-8y+12=0

Lösung

leitkurve

x^{2} + 4 x - 8 y + 12 = 0

Lösung

y = - 1

Schritte zur Lösung

Rewrite

x^{2} + 4 x - 8 y + 12 = 0

in the standard form

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

(h, k) = (- 2, 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

(- 2, 1)

y-coordinate

y = 1 - p

y = 1 - 2

Fasse zusammen

y = - 1
