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

Lösung

leitkurve

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

Lösung

x = - \frac{5}{2}

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

x-coordinate

x = - 3 - p

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

Fasse zusammen

x = - \frac{5}{2}
