foki-x^2+4x+5

Lösung

foki

- x^{2} + 4 x + 5

Lösung

(2, \frac{35}{4})

Schritte zur Lösung

Rewrite

y = - x^{2} + 4 x + 5

in the standard form

4 (- \frac{1}{4}) (y - 9) = (x - 2)^{2}

(h, k) = (2, 9), p = - \frac{1}{4}

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

p

from the center

(2, 9)

along the y-axis

(2, 9 + p)

= (2, 9 + (- \frac{1}{4}))
