foki x^2+6x-7

Lösung

foki

x^{2} + 6 x - 7

Lösung

(- 3, - \frac{63}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 6 x - 7

in the standard form

4 \cdot \frac{1}{4} (y - (- 16)) = (x - (- 3))^{2}

(h, k) = (- 3, - 16), p = \frac{1}{4}

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

p

from the center

(- 3, - 16)

along the y-axis

(- 3, - 16 + p)

= (- 3, - 16 + \frac{1}{4})
