leitkurve+x^2-6x-7

Lösung

leitkurve

+ x^{2} - 6 x - 7

Lösung

y = - \frac{65}{4}

Schritte zur Lösung

Rewrite

y = x^{2} - 6 x - 7

in the standard form

4 \cdot \frac{1}{4} (y - (- 16)) = (x - 3)^{2}

(h, k) = (3, - 16), 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

(3, - 16)

y-coordinate

y = - 16 - p

y = - 16 - \frac{1}{4}

Fasse zusammen

y = - \frac{65}{4}
