foki y=4+2x-x^2

Lösung

foki

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

Lösung

(1, \frac{19}{4})

Schritte zur Lösung

Rewrite

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

in the standard form

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

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

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}{4}))
