foki 3x^2+19x-40

Lösung

foki

3 x^{2} + 19 x - 40

Lösung

(- \frac{19}{6}, - 70)

Schritte zur Lösung

Rewrite

y = 3 x^{2} + 19 x - 40

in the standard form

4 \cdot \frac{1}{12} (y - (- \frac{841}{12})) = (x - (- \frac{19}{6}))^{2}

(h, k) = (- \frac{19}{6}, - \frac{841}{12}), p = \frac{1}{12}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(- \frac{19}{6}, - \frac{841}{12})

along the y-axis

(- \frac{19}{6}, - \frac{841}{12} + p)

= (- \frac{19}{6}, - \frac{841}{12} + \frac{1}{12})

Fasse zusammen
