leitkurve y=-4x^2-12x-8

Lösung

leitkurve

y = - 4 x^{2} - 12 x - 8

Lösung

y = \frac{17}{16}

Schritte zur Lösung

Rewrite

y = - 4 x^{2} - 12 x - 8

in the standard form

4 (- \frac{1}{16}) (y - 1) = (x - (- \frac{3}{2}))^{2}

(h, k) = (- \frac{3}{2}, 1), p = - \frac{1}{16}

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}, 1)

y-coordinate

y = 1 - p

y = 1 - (- \frac{1}{16})

Fasse zusammen

y = \frac{17}{16}
