leitkurve y=7x^2-3

Lösung

leitkurve

y = 7 x^{2} - 3

Lösung

y = - \frac{85}{28}

Schritte zur Lösung

Rewrite

y = 7 x^{2} - 3

in the standard form:

4 \cdot \frac{1}{28} (y - (- 3)) = (x - 0)^{2}

(h, k) = (0, - 3), p = \frac{1}{28}

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, - 3)

y-coordinate

y = - 3 - p

y = - 3 - \frac{1}{28}

Fasse zusammen

y = - \frac{85}{28}
