foki-x^2+4x

Lösung

foki

- x^{2} + 4 x

Lösung

(2, \frac{15}{4})

Schritte zur Lösung

Rewrite

y = - x^{2} + 4 x

in the standard form

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

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

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

p

from the center

(2, 4)

along the y-axis

(2, 4 + p)

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