leitkurve (x-3)^2=4(y+5)

Lösung

leitkurve

(x - 3)^{2} = 4 (y + 5)

Lösung

y = - 6

Schritte zur Lösung

Rewrite

(x - 3)^{2} = 4 (y + 5)

in the standard form:

4 \cdot 1 \cdot (y - (- 5)) = (x - 3)^{2}

(h, k) = (3, - 5), 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, - 5)

y-coordinate

y = - 5 - p

y = - 5 - 1

Fasse zusammen

y = - 6
