x^2=-80y

Lösung

x^{2} = - 80 y

(h, k) = (0, 0), p = - 20

Schritte zur Lösung

x^{2} = - 80 y

Rewrite

x^{2} = - 80 y

in the standard form:

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

Therefore parabola properties are:

(h, k) = (0, 0), p = - 20

y \leq - 2 x^{2} + 4 x - 1

x 3 x = 20 - 4 y

- 9 x^{2} - 7 y - 3 = 0

y = 1.9 x^{2} - 3.86 x + 15.25 y

Z^{1} = 4 + J^{2}
