leitkurve (x+1)^2=-12(y-6)

Lösung

leitkurve

(x + 1)^{2} = - 12 (y - 6)

Lösung

y = 9

Schritte zur Lösung

Rewrite

(x + 1)^{2} = - 12 (y - 6)

in the standard form:

4 (- 3) (y - 6) = (x - (- 1))^{2}

(h, k) = (- 1, 6), 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

(- 1, 6)

y-coordinate

y = 6 - p

y = 6 - (- 3)

Fasse zusammen

y = 9
