foki-2x^2-12x-23

Lösung

foki

- 2 x^{2} - 12 x - 23

Lösung

(- 3, - \frac{41}{8})

Schritte zur Lösung

Rewrite

y = - 2 x^{2} - 12 x - 23

in the standard form

4 (- \frac{1}{8}) (y - (- 5)) = (x - (- 3))^{2}

(h, k) = (- 3, - 5), p = - \frac{1}{8}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(- 3, - 5)

along the y-axis

(- 3, - 5 + p)

= (- 3, - 5 + (- \frac{1}{8}))

Fasse zusammen

(- 3, - \frac{41}{8})
