foki 2x^2-x

Lösung

foki

2 x^{2} - x

Lösung

(\frac{1}{4}, 0)

Schritte zur Lösung

Rewrite

y = 2 x^{2} - x

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{1}{8})) = (x - \frac{1}{4})^{2}

(h, k) = (\frac{1}{4}, - \frac{1}{8}), p = \frac{1}{8}

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

p

from the center

(\frac{1}{4}, - \frac{1}{8})

along the y-axis

(\frac{1}{4}, - \frac{1}{8} + p)

= (\frac{1}{4}, - \frac{1}{8} + \frac{1}{8})
