leitkurve 2x^2-x

Lösung

leitkurve

2 x^{2} - x

Lösung

y = - \frac{1}{4}

Schritte zur Lösung

Rewrite

y = 2 x^{2} - x

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{1}{8})) = (x - \frac{1}{4})^{2}

(h, k) = (\frac{1}{4}, - \frac{1}{8}), p = \frac{1}{8}

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

(\frac{1}{4}, - \frac{1}{8})

y-coordinate

y = - \frac{1}{8} - p

y = - \frac{1}{8} - \frac{1}{8}

Fasse zusammen

y = - \frac{1}{4}
