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 \cdot \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})
