foki 2x^2+4x-16

Lösung

foki

2 x^{2} + 4 x - 16

Lösung

(- 1, - \frac{143}{8})

Schritte zur Lösung

Rewrite

y = 2 x^{2} + 4 x - 16

in the standard form

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

(h, k) = (- 1, - 18), p = \frac{1}{8}

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

p

from the center

(- 1, - 18)

along the y-axis

(- 1, - 18 + p)

= (- 1, - 18 + \frac{1}{8})

Fasse zusammen
