leitkurve y=3x^2-2

Lösung

leitkurve

y = 3 x^{2} - 2

Lösung

y = - \frac{25}{12}

Schritte zur Lösung

Rewrite

y = 3 x^{2} - 2

in the standard form:

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

(h, k) = (0, - 2), 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, - 2)

y-coordinate

y = - 2 - p

y = - 2 - \frac{1}{12}

Fasse zusammen

y = - \frac{25}{12}
