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

Lösung

leitkurve

x = (- y - 1) (y + 3)

Lösung

x = \frac{5}{4}

Schritte zur Lösung

Rewrite

x = (- y - 1) (y + 3)

in the standard form

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

(h, k) = (1, - 2), p = - \frac{1}{4}

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

(1, - 2)

x-coordinate

x = 1 - p

x = 1 - (- \frac{1}{4})

Fasse zusammen

x = \frac{5}{4}
