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

Lösung

foki

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

Lösung

(- 3, - 2)

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

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

p

from the center

(- 2, - 2)

along the x-axis

(- 2 + p, - 2)

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