foki 9-x^2

Lösung

foki

9 - x^{2}

Lösung

(0, \frac{35}{4})

Schritte zur Lösung

Rewrite

y = 9 - x^{2}

in the standard form:

4 (- \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}))
