leitkurve x^2+a

Lösung

leitkurve

x^{2} + a

Lösung

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

Schritte zur Lösung

Rewrite

y = x^{2} + a

in the standard form:

4 \cdot \frac{1}{4} (y - a) = (x - 0)^{2}

(h, k) = (0, a), 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

(0, a)

y-coordinate

y = a - p

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