foki y=x^2-x-2

Lösung

foki

y = x^{2} - x - 2

Lösung

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

Schritte zur Lösung

Rewrite

y = x^{2} - x - 2

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{9}{4})) = (x - \frac{1}{2})^{2}

(h, k) = (\frac{1}{2}, - \frac{9}{4}), p = \frac{1}{4}

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

p

from the center

(\frac{1}{2}, - \frac{9}{4})

along the y-axis

(\frac{1}{2}, - \frac{9}{4} + p)

= (\frac{1}{2}, - \frac{9}{4} + \frac{1}{4})
