leitkurve 4x^2-25

Lösung

leitkurve

4 x^{2} - 25

Lösung

y = - \frac{401}{16}

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 25

in the standard form:

4 \cdot \frac{1}{16} (y - (- 25)) = (x - 0)^{2}

(h, k) = (0, - 25), p = \frac{1}{16}

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, - 25)

y-coordinate

y = - 25 - p

y = - 25 - \frac{1}{16}

Fasse zusammen

y = - \frac{401}{16}
