foki 4x^2-4x+21

Lösung

foki

4 x^{2} - 4 x + 21

Lösung

(\frac{1}{2}, \frac{321}{16})

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 4 x + 21

in the standard form

4 \cdot \frac{1}{16} (y - 20) = (x - \frac{1}{2})^{2}

(h, k) = (\frac{1}{2}, 20), p = \frac{1}{16}

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

p

from the center

(\frac{1}{2}, 20)

along the y-axis

(\frac{1}{2}, 20 + p)

= (\frac{1}{2}, 20 + \frac{1}{16})
