foki (x+3)^2-8

Lösung

foki

(x + 3)^{2} - 8

Lösung

(- 3, - \frac{31}{4})

Schritte zur Lösung

Rewrite

y = (x + 3)^{2} - 8

in the standard form:

4 \cdot \frac{1}{4} (y - (- 8)) = (x - (- 3))^{2}

(h, k) = (- 3, - 8), p = \frac{1}{4}

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

p

from the center

(- 3, - 8)

along the y-axis

(- 3, - 8 + p)

= (- 3, - 8 + \frac{1}{4})

Fasse zusammen
