leitkurve-2x^2-24x-54

Lösung

leitkurve

- 2 x^{2} - 24 x - 54

Lösung

y = \frac{145}{8}

Schritte zur Lösung

Rewrite

y = - 2 x^{2} - 24 x - 54

in the standard form

4 (- \frac{1}{8}) (y - 18) = (x - (- 6))^{2}

(h, k) = (- 6, 18), 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

(- 6, 18)

y-coordinate

y = 18 - p

y = 18 - (- \frac{1}{8})

Fasse zusammen

y = \frac{145}{8}
