leitkurve (y+2)^2=-16(x+9)

Lösung

leitkurve

(y + 2)^{2} = - 16 (x + 9)

Lösung

x = - 5

Schritte zur Lösung

Rewrite

(y + 2)^{2} = - 16 (x + 9)

in the standard form:

4 (- 4) (x - (- 9)) = (y - (- 2))^{2}

(h, k) = (- 9, - 2), p = - 4

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

(- 9, - 2)

x-coordinate

x = - 9 - p

x = - 9 - (- 4)

Fasse zusammen

x = - 5
