foki y=-x^2

Lösung

foki

y = - x^{2}

Lösung

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

Schritte zur Lösung

Rewrite

y = - x^{2}

in the standard form:

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

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

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

p

from the center

(0, 0)

along the y-axis

(0, 0 + p)

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