leitkurve x^2+4x-y+1=0

Lösung

leitkurve

x^{2} + 4 x - y + 1 = 0

Lösung

y = - \frac{13}{4}

Schritte zur Lösung

Rewrite

x^{2} + 4 x - y + 1 = 0

in the standard form

4 \cdot \frac{1}{4} (y - (- 3)) = (x - (- 2))^{2}

(h, k) = (- 2, - 3), p = \frac{1}{4}

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

(- 2, - 3)

y-coordinate

y = - 3 - p

y = - 3 - \frac{1}{4}

Fasse zusammen

y = - \frac{13}{4}
