leitkurve-2x^2+4x-2

Lösung

leitkurve

- 2 x^{2} + 4 x - 2

Lösung

y = \frac{1}{8}

Schritte zur Lösung

Rewrite

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

in the standard form

4 (- \frac{1}{8}) (y - 0) = (x - 1)^{2}

(h, k) = (1, 0), 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

(1, 0)

y-coordinate

y = 0 - p

y = 0 - (- \frac{1}{8})

Fasse zusammen

y = \frac{1}{8}
