leitkurve x^2+8x+18

Lösung

leitkurve

x^{2} + 8 x + 18

Lösung

y = \frac{7}{4}

Schritte zur Lösung

Rewrite

y = x^{2} + 8 x + 18

in the standard form

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

(h, k) = (- 4, 2), 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

(- 4, 2)

y-coordinate

y = 2 - p

y = 2 - \frac{1}{4}

Fasse zusammen

y = \frac{7}{4}
