foki y=8(x+2)^2-1

Lösung

foki

y = 8 (x + 2)^{2} - 1

Lösung

(- 2, - \frac{31}{32})

Schritte zur Lösung

Rewrite

y = 8 (x + 2)^{2} - 1

in the standard form:

4 \cdot \frac{1}{32} (y - (- 1)) = (x - (- 2))^{2}

(h, k) = (- 2, - 1), p = \frac{1}{32}

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

p

from the center

(- 2, - 1)

along the y-axis

(- 2, - 1 + p)

= (- 2, - 1 + \frac{1}{32})

Fasse zusammen

(- 2, - \frac{31}{32})
