leitkurve x=-1/20 (y+6)^2-7

Lösung

leitkurve

x = - \frac{1}{20} (y + 6)^{2} - 7

Lösung

x = - 2

Schritte zur Lösung

Rewrite

x = - \frac{1}{20} (y + 6)^{2} - 7

in the standard form:

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

(h, k) = (- 7, - 6), p = - 5

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 - (- 5)

Fasse zusammen

x = - 2
