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

Lösung

leitkurve

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

Lösung

y = - 5

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

y-coordinate

y = - 4 - p

y = - 4 - 1

Fasse zusammen

y = - 5
