foki 2x^2-8x+3

Lösung

foki

2 x^{2} - 8 x + 3

Lösung

(2, - \frac{39}{8})

Schritte zur Lösung

Rewrite

y = 2 x^{2} - 8 x + 3

in the standard form

4 \cdot \frac{1}{8} (y - (- 5)) = (x - 2)^{2}

(h, k) = (2, - 5), p = \frac{1}{8}

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

p

from the center

(2, - 5)

along the y-axis

(2, - 5 + p)

= (2, - 5 + \frac{1}{8})
