leitkurve y=(x+3)(x-1)

Lösung

leitkurve

y = (x + 3) (x - 1)

Lösung

y = - \frac{17}{4}

Schritte zur Lösung

Rewrite

y = (x + 3) (x - 1)

in the standard form

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

(h, k) = (- 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

(- 1, - 4)

y-coordinate

y = - 4 - p

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

Fasse zusammen

y = - \frac{17}{4}
