foki 3x^2+2x+6

Lösung

foki

3 x^{2} + 2 x + 6

Lösung

(- \frac{1}{3}, \frac{23}{4})

Schritte zur Lösung

Rewrite

y = 3 x^{2} + 2 x + 6

in the standard form

4 \cdot \frac{1}{12} (y - \frac{17}{3}) = (x - (- \frac{1}{3}))^{2}

(h, k) = (- \frac{1}{3}, \frac{17}{3}), p = \frac{1}{12}

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

p

from the center

(- \frac{1}{3}, \frac{17}{3})

along the y-axis

(- \frac{1}{3}, \frac{17}{3} + p)

= (- \frac{1}{3}, \frac{17}{3} + \frac{1}{12})

Fasse zusammen
