foki x^2-16

Lösung

foki

x^{2} - 16

Lösung

(0, - \frac{63}{4})

Schritte zur Lösung

Rewrite

y = x^{2} - 16

in the standard form:

4 \cdot \frac{1}{4} (y - (- 16)) = (x - 0)^{2}

(h, k) = (0, - 16), p = \frac{1}{4}

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

p

from the center

(0, - 16)

along the y-axis

(0, - 16 + p)

= (0, - 16 + \frac{1}{4})
