foki 3(x-1)(x+2)

Lösung

foki

3 (x - 1) (x + 2)

Lösung

(- \frac{1}{2}, - \frac{20}{3})

Schritte zur Lösung

Rewrite

y = 3 (x - 1) (x + 2)

in the standard form

4 \cdot \frac{1}{12} (y - (- \frac{27}{4})) = (x - (- \frac{1}{2}))^{2}

(h, k) = (- \frac{1}{2}, - \frac{27}{4}), p = \frac{1}{12}

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

p

from the center

(- \frac{1}{2}, - \frac{27}{4})

along the y-axis

(- \frac{1}{2}, - \frac{27}{4} + p)

= (- \frac{1}{2}, - \frac{27}{4} + \frac{1}{12})

Fasse zusammen

(- \frac{1}{2}, - \frac{20}{3})
