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

Lösung

leitkurve

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

Lösung

y = - \frac{5}{2}

Schritte zur Lösung

Rewrite

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

in the standard form:

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

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

(- 3, - 2)

y-coordinate

y = - 2 - p

y = - 2 - \frac{1}{2}

Fasse zusammen

y = - \frac{5}{2}
