foki-3x^2+5x-4

Lösung

foki

- 3 x^{2} + 5 x - 4

Lösung

(\frac{5}{6}, - 2)

Schritte zur Lösung

Rewrite

y = - 3 x^{2} + 5 x - 4

in the standard form

4 (- \frac{1}{12}) (y - (- \frac{23}{12})) = (x - \frac{5}{6})^{2}

(h, k) = (\frac{5}{6}, - \frac{23}{12}), p = - \frac{1}{12}

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

p

from the center

(\frac{5}{6}, - \frac{23}{12})

along the y-axis

(\frac{5}{6}, - \frac{23}{12} + p)

= (\frac{5}{6}, - \frac{23}{12} + (- \frac{1}{12}))
