leitkurve x^2+2x+2

Lösung

leitkurve

x^{2} + 2 x + 2

Lösung

y = \frac{3}{4}

Schritte zur Lösung

Rewrite

y = x^{2} + 2 x + 2

in the standard form

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

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

(- 1, 1)

y-coordinate

y = 1 - p

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

Fasse zusammen

y = \frac{3}{4}
