foki y=-2x+x(x-2)-2x(x-1)-(x-3)

Lösung

foki

y = - 2 x + x (x - 2) - 2 x (x - 1) - (x - 3)

Lösung

(- \frac{3}{2}, 5)

Schritte zur Lösung

Rewrite

y = - 2 x + x (x - 2) - 2 x (x - 1) - (x - 3)

in the standard form

4 (- \frac{1}{4}) (y - \frac{21}{4}) = (x - (- \frac{3}{2}))^{2}

(h, k) = (- \frac{3}{2}, \frac{21}{4}), p = - \frac{1}{4}

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

p

from the center

(- \frac{3}{2}, \frac{21}{4})

along the y-axis

(- \frac{3}{2}, \frac{21}{4} + p)

= (- \frac{3}{2}, \frac{21}{4} + (- \frac{1}{4}))
