leitkurve (y-7)^2=-12(x+1)

Lösung

leitkurve

(y - 7)^{2} = - 12 (x + 1)

Lösung

x = 2

Schritte zur Lösung

Rewrite

(y - 7)^{2} = - 12 (x + 1)

in the standard form:

4 (- 3) (x - (- 1)) = (y - 7)^{2}

(h, k) = (- 1, 7), p = - 3

Parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis, a distance

- p

from the center

(- 1, 7)

x-coordinate

x = - 1 - p

x = - 1 - (- 3)

Fasse zusammen

x = 2
