foki y=4x+4x-2+x^2-3

Lösung

foki

y = 4 x + 4 x - 2 + x^{2} - 3

Lösung

(- 4, - \frac{83}{4})

Schritte zur Lösung

Rewrite

y = 4 x + 4 x - 2 + x^{2} - 3

in the standard form

4 \cdot \frac{1}{4} (y - (- 21)) = (x - (- 4))^{2}

(h, k) = (- 4, - 21), p = \frac{1}{4}

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

p

from the center

(- 4, - 21)

along the y-axis

(- 4, - 21 + p)

= (- 4, - 21 + \frac{1}{4})
