foki (x+3)^2=-y

Lösung

foki

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

Lösung

(- 3, - \frac{1}{4})

Schritte zur Lösung

Rewrite

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

in the standard form:

4 (- \frac{1}{4}) (y - 0) = (x - (- 3))^{2}

(h, k) = (- 3, 0), p = - \frac{1}{4}

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

p

from the center

(- 3, 0)

along the y-axis

(- 3, 0 + p)

= (- 3, 0 + (- \frac{1}{4}))
