leitkurve x^2+6x-8

Lösung

leitkurve

x^{2} + 6 x - 8

Lösung

y = - \frac{69}{4}

Schritte zur Lösung

Rewrite

y = x^{2} + 6 x - 8

in the standard form

4 \cdot \frac{1}{4} (y - (- 17)) = (x - (- 3))^{2}

(h, k) = (- 3, - 17), 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, - 17)

y-coordinate

y = - 17 - p

y = - 17 - \frac{1}{4}

Fasse zusammen

y = - \frac{69}{4}
