foki-2x^2+4x-7

Lösung

foki

- 2 x^{2} + 4 x - 7

Lösung

(1, - \frac{41}{8})

Schritte zur Lösung

Rewrite

y = - 2 x^{2} + 4 x - 7

in the standard form

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

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

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

p

from the center

(1, - 5)

along the y-axis

(1, - 5 + p)

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

Fasse zusammen
