foki y=-x^2+2x-5

Lösung

foki

y = - x^{2} + 2 x - 5

Lösung

(1, - \frac{17}{4})

Schritte zur Lösung

Rewrite

y = - x^{2} + 2 x - 5

in the standard form

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

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

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

p

from the center

(1, - 4)

along the y-axis

(1, - 4 + p)

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