foki y=2x^2-1-(5x-6)

Lösung

foki

y = 2 x^{2} - 1 - (5 x - 6)

Lösung

(\frac{5}{4}, 2)

Schritte zur Lösung

Rewrite

y = 2 x^{2} - 1 - (5 x - 6)

in the standard form

4 \cdot \frac{1}{8} (y - \frac{15}{8}) = (x - \frac{5}{4})^{2}

(h, k) = (\frac{5}{4}, \frac{15}{8}), p = \frac{1}{8}

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

p

from the center

(\frac{5}{4}, \frac{15}{8})

along the y-axis

(\frac{5}{4}, \frac{15}{8} + p)

= (\frac{5}{4}, \frac{15}{8} + \frac{1}{8})
