foki 2x^2-4x+15

Lösung

foki

2 x^{2} - 4 x + 15

Lösung

(1, \frac{105}{8})

Schritte zur Lösung

Rewrite

y = 2 x^{2} - 4 x + 15

in the standard form

4 \cdot \frac{1}{8} (y - 13) = (x - 1)^{2}

(h, k) = (1, 13), p = \frac{1}{8}

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

p

from the center

(1, 13)

along the y-axis

(1, 13 + p)

= (1, 13 + \frac{1}{8})
