leitkurve x=-((y+3)^2)/(20)+1

Lösung

leitkurve

x = - \frac{( y + 3 ) ^{2}}{20} + 1

Lösung

x = 6

Schritte zur Lösung

Rewrite

x = - \frac{( y + 3 ) ^{2}}{20} + 1

in the standard form:

4 (- 5) (x - 1) = (y - (- 3))^{2}

(h, k) = (1, - 3), 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

(1, - 3)

x-coordinate

x = 1 - p

x = 1 - (- 5)

Fasse zusammen

x = 6
