leitkurve (x-4)^2=-8(y+3)

Lösung

leitkurve

(x - 4)^{2} = - 8 (y + 3)

Lösung

y = - 1

Schritte zur Lösung

Rewrite

(x - 4)^{2} = - 8 (y + 3)

in the standard form:

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

(h, k) = (4, - 3), 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

(4, - 3)

y-coordinate

y = - 3 - p

y = - 3 - (- 2)

Fasse zusammen

y = - 1
