foki y=(x+9)(x+8)

Lösung

foki

y = (x + 9) (x + 8)

Lösung

(- \frac{17}{2}, 0)

Schritte zur Lösung

Rewrite

y = (x + 9) (x + 8)

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{1}{4})) = (x - (- \frac{17}{2}))^{2}

(h, k) = (- \frac{17}{2}, - \frac{1}{4}), p = \frac{1}{4}

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

p

from the center

(- \frac{17}{2}, - \frac{1}{4})

along the y-axis

(- \frac{17}{2}, - \frac{1}{4} + p)

= (- \frac{17}{2}, - \frac{1}{4} + \frac{1}{4})

Fasse zusammen

(- \frac{17}{2}, 0)
