foki y=x^2+8x+18

Lösung

foki

y = x^{2} + 8 x + 18

Lösung

(- 4, \frac{9}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 8 x + 18

in the standard form

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

(h, k) = (- 4, 2), p = \frac{1}{4}

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

p

from the center

(- 4, 2)

along the y-axis

(- 4, 2 + p)

= (- 4, 2 + \frac{1}{4})
