leitkurve (x+1)^2=12(y-3)

Lösung

leitkurve

(x + 1)^{2} = 12 (y - 3)

Lösung

y = 0

Schritte zur Lösung

Rewrite

(x + 1)^{2} = 12 (y - 3)

in the standard form:

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

(h, k) = (- 1, 3), p = 3

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

(- 1, 3)

y-coordinate

y = 3 - p

y = 3 - 3

Fasse zusammen

y = 0
