x^2+9y=4

Lösung

x^{2} + 9 y = 4

(h, k) = (0, \frac{4}{9}), p = - \frac{9}{4}

Schritte zur Lösung

x^{2} + 9 y = 4

Rewrite

x^{2} + 9 y = 4

in the standard form:

4 (- \frac{9}{4}) (y - \frac{4}{9}) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, \frac{4}{9}), p = - \frac{9}{4}

(y + 5)^{2} = - 8 (x - 4)

(x + 3)^{2} = 8 (y - 4)

x^{2} + 2 y - 2 x + 8 y + 5 = 0

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

y = \frac{2 x}{y}
