leitkurve 3x^2+18

Lösung

leitkurve

3 x^{2} + 18

Lösung

y = \frac{215}{12}

Schritte zur Lösung

Rewrite

y = 3 x^{2} + 18

in the standard form:

4 \cdot \frac{1}{12} (y - 18) = (x - 0)^{2}

(h, k) = (0, 18), 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, 18)

y-coordinate

y = 18 - p

y = 18 - \frac{1}{12}

Fasse zusammen

y = \frac{215}{12}
