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

Lösung

foki

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

Lösung

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

Schritte zur Lösung

Rewrite

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

in the standard form

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

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

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

p

from the center

(- 1, 1)

along the y-axis

(- 1, 1 + p)

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

f oc i - y^{2} = 6 y + x

foki (y+1)^2=16(x-3)

f oc i (y + 1)^{2} = 16 (x - 3)

foki (x+1)(x-5)
