foki 4x^2+2x+4

Lösung

foki

4 x^{2} + 2 x + 4

Lösung

(- \frac{1}{4}, \frac{61}{16})

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{16} (y - \frac{15}{4}) = (x - (- \frac{1}{4}))^{2}

(h, k) = (- \frac{1}{4}, \frac{15}{4}), p = \frac{1}{16}

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

p

from the center

(- \frac{1}{4}, \frac{15}{4})

along the y-axis

(- \frac{1}{4}, \frac{15}{4} + p)

= (- \frac{1}{4}, \frac{15}{4} + \frac{1}{16})
