foki 1/2 (1-2y-y^2)

Lösung

foki

\frac{1}{2} (1 - 2 y - y^{2})

Lösung

(\frac{1}{2}, - 1)

Schritte zur Lösung

Rewrite

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

in the standard form

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

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

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

p

from the center

(1, - 1)

along the x-axis

(1 + p, - 1)

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