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

Lösung

leitkurve

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

Lösung

y = 1

Schritte zur Lösung

Rewrite

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

in the standard form

4 (- 1) (y - 0) = (x - (- 2))^{2}

(h, k) = (- 2, 0), p = - 1

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, 0)

y-coordinate

y = 0 - p

y = 0 - (- 1)

Fasse zusammen

y = 1
