c c/a =(-1)/2

Lösung

c \frac{c}{a} = \frac{- 1}{2}

(h, k) = (0, 0), p = - \frac{1}{8}

Schritte zur Lösung

c \frac{c}{a} = \frac{- 1}{2}

Rewrite

c \frac{c}{a} - \frac{- 1}{2} = 0

in the standard form

4 (- \frac{1}{8}) (a - 0) = (c - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, 0), p = - \frac{1}{8}

- 5 = - x^{2} + y + 16 x - 16

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

5 x^{2} - x + 3 y + 6 = 0

y 2 y = 10 x - 5

y^{2} - 3 z = 0
