leitkurve (3x-4)(4x-3)-2x

Lösung

leitkurve

(3 x - 4) (4 x - 3) - 2 x

Lösung

y = - \frac{77}{24}

Schritte zur Lösung

Rewrite

y = (3 x - 4) (4 x - 3) - 2 x

in the standard form

4 \cdot \frac{1}{48} (y - (- \frac{51}{16})) = (x - \frac{9}{8})^{2}

(h, k) = (\frac{9}{8}, - \frac{51}{16}), p = \frac{1}{48}

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{9}{8}, - \frac{51}{16})

y-coordinate

y = - \frac{51}{16} - p

y = - \frac{51}{16} - \frac{1}{48}

Fasse zusammen

y = - \frac{77}{24}
