leitkurve y=(x-4)(x-7)

Lösung

leitkurve

y = (x - 4) (x - 7)

Lösung

y = - \frac{5}{2}

Schritte zur Lösung

Rewrite

y = (x - 4) (x - 7)

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{9}{4})) = (x - \frac{11}{2})^{2}

(h, k) = (\frac{11}{2}, - \frac{9}{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

(\frac{11}{2}, - \frac{9}{4})

y-coordinate

y = - \frac{9}{4} - p

y = - \frac{9}{4} - \frac{1}{4}

Fasse zusammen

y = - \frac{5}{2}
