leitkurve (x+4)^2=-12(y-2)

Lösung

leitkurve

(x + 4)^{2} = - 12 (y - 2)

Lösung

y = 5

Schritte zur Lösung

Rewrite

(x + 4)^{2} = - 12 (y - 2)

in the standard form:

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

(h, k) = (- 4, 2), p = - 3

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, 2)

y-coordinate

y = 2 - p

y = 2 - (- 3)

Fasse zusammen

y = 5
