foki 2x^2+3x-1

Lösung

foki

2 x^{2} + 3 x - 1

Lösung

(- \frac{3}{4}, - 2)

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{17}{8})) = (x - (- \frac{3}{4}))^{2}

(h, k) = (- \frac{3}{4}, - \frac{17}{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{17}{8})

along the y-axis

(- \frac{3}{4}, - \frac{17}{8} + p)

= (- \frac{3}{4}, - \frac{17}{8} + \frac{1}{8})
