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

Lösung

leitkurve

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

Lösung

y = - 4

Schritte zur Lösung

Rewrite

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

in the standard form:

4 \cdot 2 (y - (- 2)) = (x - 4)^{2}

(h, k) = (4, - 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

(4, - 2)

y-coordinate

y = - 2 - p

y = - 2 - 2

Fasse zusammen

y = - 4
