leitkurve y=x^2+6x+8

Lösung

leitkurve

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

Lösung

y = - \frac{5}{4}

Schritte zur Lösung

Rewrite

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

in the standard form

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

(h, k) = (- 3, - 1), 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, - 1)

y-coordinate

y = - 1 - p

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

Fasse zusammen

y = - \frac{5}{4}
