foki y=4x^2-8x+1

Lösung

foki

y = 4 x^{2} - 8 x + 1

Lösung

(1, - \frac{47}{16})

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 8 x + 1

in the standard form

4 \cdot \frac{1}{16} (y - (- 3)) = (x - 1)^{2}

(h, k) = (1, - 3), p = \frac{1}{16}

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

p

from the center

(1, - 3)

along the y-axis

(1, - 3 + p)

= (1, - 3 + \frac{1}{16})

Fasse zusammen
