leitkurve y=-3x^2

Lösung

leitkurve

y = - 3 x^{2}

Lösung

y = \frac{1}{12}

Schritte zur Lösung

Rewrite

y = - 3 x^{2}

in the standard form:

4 (- \frac{1}{12}) (y - 0) = (x - 0)^{2}

(h, k) = (0, 0), p = - \frac{1}{12}

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}{12})

Fasse zusammen

y = \frac{1}{12}
