leitkurve (x-3)^2=-4(y+1)

Lösung

leitkurve

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

Lösung

y = 0

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

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, - 1)

y-coordinate

y = - 1 - p

y = - 1 - (- 1)

Fasse zusammen

y = 0
