foki 4x^2+8x

Lösung

foki

4 x^{2} + 8 x

Lösung

(- 1, - \frac{63}{16})

Schritte zur Lösung

Rewrite

y = 4 x^{2} + 8 x

in the standard form

4 \cdot \frac{1}{16} (y - (- 4)) = (x - (- 1))^{2}

(h, k) = (- 1, - 4), p = \frac{1}{16}

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

p

from the center

(- 1, - 4)

along the y-axis

(- 1, - 4 + p)

= (- 1, - 4 + \frac{1}{16})

Fasse zusammen
