foki y=-4x^2+1

Lösung

foki

y = - 4 x^{2} + 1

Lösung

(0, \frac{15}{16})

Schritte zur Lösung

Rewrite

y = - 4 x^{2} + 1

in the standard form:

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

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

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

p

from the center

(0, 1)

along the y-axis

(0, 1 + p)

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