foki s^2+4s+20

Lösung

foki

s^{2} + 4 s + 20

Lösung

(- 2, \frac{65}{4})

Schritte zur Lösung

Rewrite

y = s^{2} + 4 s + 20

in the standard form

4 \cdot \frac{1}{4} (y - 16) = (s - (- 2))^{2}

(h, k) = (- 2, 16), p = \frac{1}{4}

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

p

from the center

(- 2, 16)

along the y-axis

(- 2, 16 + p)

= (- 2, 16 + \frac{1}{4})

Fasse zusammen

(- 2, \frac{65}{4})
