leitkurve x=-1/4 (y+6)^2+7

Lösung

leitkurve

x = - \frac{1}{4} (y + 6)^{2} + 7

Lösung

x = 8

Schritte zur Lösung

Rewrite

x = - \frac{1}{4} (y + 6)^{2} + 7

in the standard form:

4 (- 1) (x - 7) = (y - (- 6))^{2}

(h, k) = (7, - 6), p = - 1

Parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis, a distance

- p

from the center

(7, - 6)

x-coordinate

x = 7 - p

x = 7 - (- 1)

Fasse zusammen

x = 8
