leitkurve (x+5)^2=-20(y-2)

Lösung

leitkurve

(x + 5)^{2} = - 20 (y - 2)

Lösung

y = 7

Schritte zur Lösung

Rewrite

(x + 5)^{2} = - 20 (y - 2)

in the standard form:

4 (- 5) (y - 2) = (x - (- 5))^{2}

(h, k) = (- 5, 2), p = - 5

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

(- 5, 2)

y-coordinate

y = 2 - p

y = 2 - (- 5)

Fasse zusammen

y = 7
