foki-3x^2+3x-13

Lösung

foki

- 3 x^{2} + 3 x - 13

Lösung

(\frac{1}{2}, - \frac{37}{3})

Schritte zur Lösung

Rewrite

y = - 3 x^{2} + 3 x - 13

in the standard form

4 (- \frac{1}{12}) (y - (- \frac{49}{4})) = (x - \frac{1}{2})^{2}

(h, k) = (\frac{1}{2}, - \frac{49}{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{49}{4})

along the y-axis

(\frac{1}{2}, - \frac{49}{4} + p)

= (\frac{1}{2}, - \frac{49}{4} + (- \frac{1}{12}))
