leitkurve-3x^2+17x-20

Lösung

leitkurve

- 3 x^{2} + 17 x - 20

Lösung

y = \frac{25}{6}

Schritte zur Lösung

Rewrite

y = - 3 x^{2} + 17 x - 20

in the standard form

4 (- \frac{1}{12}) (y - \frac{49}{12}) = (x - \frac{17}{6})^{2}

(h, k) = (\frac{17}{6}, \frac{49}{12}), p = - \frac{1}{12}

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{17}{6}, \frac{49}{12})

y-coordinate

y = \frac{49}{12} - p

y = \frac{49}{12} - (- \frac{1}{12})

Fasse zusammen

y = \frac{25}{6}
