leitkurve-x^2-3x-2

Lösung

leitkurve

- x^{2} - 3 x - 2

Lösung

y = \frac{1}{2}

Schritte zur Lösung

Rewrite

y = - x^{2} - 3 x - 2

in the standard form

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

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

(- \frac{3}{2}, \frac{1}{4})

y-coordinate

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

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

Fasse zusammen

y = \frac{1}{2}
