foki y=x^2+6x+5

Lösung

foki

y = x^{2} + 6 x + 5

Lösung

(- 3, - \frac{15}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 6 x + 5

in the standard form

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

(h, k) = (- 3, - 4), p = \frac{1}{4}

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

p

from the center

(- 3, - 4)

along the y-axis

(- 3, - 4 + p)

= (- 3, - 4 + \frac{1}{4})
