leitkurve-1/8 (y-8)^2+2

Lösung

leitkurve

- \frac{1}{8} (y - 8)^{2} + 2

Lösung

x = 4

Schritte zur Lösung

Rewrite

x = - \frac{1}{8} (y - 8)^{2} + 2

in the standard form:

4 (- 2) (x - 2) = (y - 8)^{2}

(h, k) = (2, 8), p = - 2

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

(2, 8)

x-coordinate

x = 2 - p

x = 2 - (- 2)

Fasse zusammen

x = 4
