leitkurve-8x^2+4x

Lösung

leitkurve

- 8 x^{2} + 4 x

Lösung

y = \frac{17}{32}

Schritte zur Lösung

Rewrite

y = - 8 x^{2} + 4 x

in the standard form

4 (- \frac{1}{32}) (y - \frac{1}{2}) = (x - \frac{1}{4})^{2}

(h, k) = (\frac{1}{4}, \frac{1}{2}), p = - \frac{1}{32}

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}{2})

y-coordinate

y = \frac{1}{2} - p

y = \frac{1}{2} - (- \frac{1}{32})

Fasse zusammen

y = \frac{17}{32}
