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

Lösung

leitkurve

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

Lösung

y = 3

Schritte zur Lösung

Rewrite

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

in the standard form

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

(h, k) = (- 2, 2), 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, 2)

y-coordinate

y = 2 - p

y = 2 - (- 1)

Fasse zusammen

y = 3
