leitkurve 9x^2-4

Lösung

leitkurve

9 x^{2} - 4

Lösung

y = - \frac{145}{36}

Schritte zur Lösung

Rewrite

y = 9 x^{2} - 4

in the standard form:

4 \cdot \frac{1}{36} (y - (- 4)) = (x - 0)^{2}

(h, k) = (0, - 4), p = \frac{1}{36}

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(0, - 4)

y-coordinate

y = - 4 - p

y = - 4 - \frac{1}{36}

Fasse zusammen

y = - \frac{145}{36}
