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

Lösung

leitkurve

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

Lösung

y = - \frac{85}{4}

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - (- 21)) = (x - (- 4))^{2}

(h, k) = (- 4, - 21), 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

(- 4, - 21)

y-coordinate

y = - 21 - p

y = - 21 - \frac{1}{4}

Fasse zusammen

y = - \frac{85}{4}
