foki y^2=-28x

Lösung

foki

y^{2} = - 28 x

Lösung

(- 7, 0)

Schritte zur Lösung

Rewrite

y^{2} = - 28 x

in the standard form:

4 (- 7) (x - 0) = (y - 0)^{2}

(h, k) = (0, 0), p = - 7

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

p

from the center

(0, 0)

along the x-axis

(0 + p, 0)

= (0 + (- 7), 0)
