leitkurve y=-x^2-4x-3

Lösung

leitkurve

y = - x^{2} - 4 x - 3

Lösung

y = \frac{5}{4}

Schritte zur Lösung

Rewrite

y = - x^{2} - 4 x - 3

in the standard form

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

(h, k) = (- 2, 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

(- 2, 1)

y-coordinate

y = 1 - p

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

Fasse zusammen

y = \frac{5}{4}
