leitkurve 3x^2-10x+3

Lösung

leitkurve

3 x^{2} - 10 x + 3

Lösung

y = - \frac{65}{12}

Schritte zur Lösung

Rewrite

y = 3 x^{2} - 10 x + 3

in the standard form

4 \cdot \frac{1}{12} (y - (- \frac{16}{3})) = (x - \frac{5}{3})^{2}

(h, k) = (\frac{5}{3}, - \frac{16}{3}), 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{5}{3}, - \frac{16}{3})

y-coordinate

y = - \frac{16}{3} - p

y = - \frac{16}{3} - \frac{1}{12}

Fasse zusammen

y = - \frac{65}{12}
