Lösung

Schritte zur Lösung

Rewrite

y = - \frac{1}{4} x^{2} + 8 x - 4

in the standard form

4 (- 1) (y - 60) = (x - 16)^{2}

(h, k) = (16, 60), p = - 1

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

p

from the center

(16, 60)

along the y-axis

(16, 60 + p)

= (16, 60 + (- 1))
