foki x=-1/4 (y+2)^2

Lösung

foki

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

Lösung

(- 1, - 2)

Schritte zur Lösung

Rewrite

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

in the standard form:

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

(h, k) = (0, - 2), p = - 1

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

p

from the center

(0, - 2)

along the x-axis

(0 + p, - 2)

= (0 + (- 1), - 2)
