leitkurve (1/2-x)(-1/2-x)

Lösung

leitkurve

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

Lösung

y = - \frac{1}{2}

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{1}{4})) = (x - 0)^{2}

(h, k) = (0, - \frac{1}{4}), p = \frac{1}{4}

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

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

y-coordinate

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

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

Fasse zusammen

y = - \frac{1}{2}
