leitkurve x=(y+1)y

Lösung

leitkurve

x = (y + 1) y

Lösung

x = - \frac{1}{2}

Schritte zur Lösung

Rewrite

x = (y + 1) y

in the standard form

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

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

(- \frac{1}{4}, - \frac{1}{2})

x-coordinate

x = - \frac{1}{4} - p

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

Fasse zusammen

x = - \frac{1}{2}
