leitkurve x^2+8x-4y-36=0

Lösung

leitkurve

x^{2} + 8 x - 4 y - 36 = 0

Lösung

y = - 14

Schritte zur Lösung

Rewrite

x^{2} + 8 x - 4 y - 36 = 0

in the standard form

4 \cdot 1 \cdot (y - (- 13)) = (x - (- 4))^{2}

(h, k) = (- 4, - 13), p = 1

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, - 13)

y-coordinate

y = - 13 - p

y = - 13 - 1

Fasse zusammen

y = - 14
