leitkurve+x^2-14

Lösung

leitkurve

+ x^{2} - 14

Lösung

y = - \frac{57}{4}

Schritte zur Lösung

Rewrite

y = x^{2} - 14

in the standard form:

4 \cdot \frac{1}{4} (y - (- 14)) = (x - 0)^{2}

(h, k) = (0, - 14), p = \frac{1}{4}

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, - 14)

y-coordinate

y = - 14 - p

y = - 14 - \frac{1}{4}

Fasse zusammen

y = - \frac{57}{4}
