foki x^2+2x+1

Lösung

foki

x^{2} + 2 x + 1

Lösung

(- 1, \frac{1}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 2 x + 1

in the standard form

4 \cdot \frac{1}{4} (y - 0) = (x - (- 1))^{2}

(h, k) = (- 1, 0), p = \frac{1}{4}

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

p

from the center

(- 1, 0)

along the y-axis

(- 1, 0 + p)

= (- 1, 0 + \frac{1}{4})
