foki x^2+9

Lösung

foki

x^{2} + 9

Lösung

(0, \frac{37}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 9

in the standard form:

4 \cdot \frac{1}{4} (y - 9) = (x - 0)^{2}

(h, k) = (0, 9), p = \frac{1}{4}

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

p

from the center

(0, 9)

along the y-axis

(0, 9 + p)

= (0, 9 + \frac{1}{4})
