foki x^2+8x+15

Lösung

foki

x^{2} + 8 x + 15

Lösung

(- 4, - \frac{3}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 8 x + 15

in the standard form

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

(h, k) = (- 4, - 1), p = \frac{1}{4}

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

p

from the center

(- 4, - 1)

along the y-axis

(- 4, - 1 + p)

= (- 4, - 1 + \frac{1}{4})

Fasse zusammen
