leitkurve y=-8(x+1)^2

Lösung

leitkurve

y = - 8 (x + 1)^{2}

Lösung

y = \frac{1}{32}

Schritte zur Lösung

Rewrite

y = - 8 (x + 1)^{2}

in the standard form:

4 (- \frac{1}{32}) (y - 0) = (x - (- 1))^{2}

(h, k) = (- 1, 0), p = - \frac{1}{32}

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, 0)

y-coordinate

y = 0 - p

y = 0 - (- \frac{1}{32})

Fasse zusammen

y = \frac{1}{32}
