leitkurve y=2x^2

Lösung

leitkurve

y = 2 x^{2}

Lösung

y = - \frac{1}{8}

Schritte zur Lösung

Rewrite

y = 2 x^{2}

in the standard form:

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

(h, k) = (0, 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

(0, 0)

y-coordinate

y = 0 - p

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

Fasse zusammen

y = - \frac{1}{8}
