leitkurve y=x^2-4x-4

Lösung

leitkurve

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

Lösung

y = - \frac{33}{4}

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - (- 8)) = (x - 2)^{2}

(h, k) = (2, - 8), p = \frac{1}{4}

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

(2, - 8)

y-coordinate

y = - 8 - p

y = - 8 - \frac{1}{4}

Fasse zusammen

y = - \frac{33}{4}
