leitkurve-2x=(y+3)^2+6

Lösung

leitkurve

- 2 x = (y + 3)^{2} + 6

Lösung

x = - \frac{5}{2}

Schritte zur Lösung

Rewrite

- 2 x = (y + 3)^{2} + 6

in the standard form:

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

(h, k) = (- 3, - 3), p = - \frac{1}{2}

Parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis, a distance

- p

from the center

(- 3, - 3)

x-coordinate

x = - 3 - p

x = - 3 - (- \frac{1}{2})

Fasse zusammen

x = - \frac{5}{2}
