leitkurve-2x^2+11

Lösung

leitkurve

- 2 x^{2} + 11

Lösung

y = \frac{89}{8}

Schritte zur Lösung

Rewrite

y = - 2 x^{2} + 11

in the standard form:

4 (- \frac{1}{8}) (y - 11) = (x - 0)^{2}

(h, k) = (0, 11), 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, 11)

y-coordinate

y = 11 - p

y = 11 - (- \frac{1}{8})

Fasse zusammen

y = \frac{89}{8}
