foki-2x^2+3x-1

Lösung

foki

- 2 x^{2} + 3 x - 1

Lösung

(\frac{3}{4}, 0)

Schritte zur Lösung

Rewrite

y = - 2 x^{2} + 3 x - 1

in the standard form

4 (- \frac{1}{8}) (y - \frac{1}{8}) = (x - \frac{3}{4})^{2}

(h, k) = (\frac{3}{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{3}{4}, \frac{1}{8})

along the y-axis

(\frac{3}{4}, \frac{1}{8} + p)

= (\frac{3}{4}, \frac{1}{8} + (- \frac{1}{8}))
