leitkurve (x(x+5))/7

Lösung

leitkurve

\frac{x ( x + 5 )}{7}

Lösung

y = - \frac{37}{14}

Schritte zur Lösung

Rewrite

y = \frac{x ( x + 5 )}{7}

in the standard form

4 \cdot \frac{7}{4} (y - (- \frac{25}{28})) = (x - (- \frac{5}{2}))^{2}

(h, k) = (- \frac{5}{2}, - \frac{25}{28}), p = \frac{7}{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{5}{2}, - \frac{25}{28})

y-coordinate

y = - \frac{25}{28} - p

y = - \frac{25}{28} - \frac{7}{4}

Fasse zusammen

y = - \frac{37}{14}
