foki 2x^2-12x-5

Lösung

foki

2 x^{2} - 12 x - 5

Lösung

(3, - \frac{183}{8})

Schritte zur Lösung

Rewrite

y = 2 x^{2} - 12 x - 5

in the standard form

4 \cdot \frac{1}{8} (y - (- 23)) = (x - 3)^{2}

(h, k) = (3, - 23), p = \frac{1}{8}

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

p

from the center

(3, - 23)

along the y-axis

(3, - 23 + p)

= (3, - 23 + \frac{1}{8})

Fasse zusammen
