leitkurve (x+3)^2=-8(y+2)

Lösung

leitkurve

(x + 3)^{2} = - 8 (y + 2)

Lösung

y = 0

Schritte zur Lösung

Rewrite

(x + 3)^{2} = - 8 (y + 2)

in the standard form:

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

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

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

(- 3, - 2)

y-coordinate

y = - 2 - p

y = - 2 - (- 2)
