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

Lösung

leitkurve

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

Lösung

y = 4

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

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

(8, 2)

y-coordinate

y = 2 - p

y = 2 - (- 2)

Fasse zusammen

y = 4
