foki y=-2x^2-3

Lösung

foki

y = - 2 x^{2} - 3

Lösung

(0, - \frac{25}{8})

Schritte zur Lösung

Rewrite

y = - 2 x^{2} - 3

in the standard form:

4 (- \frac{1}{8}) (y - (- 3)) = (x - 0)^{2}

(h, k) = (0, - 3), p = - \frac{1}{8}

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

p

from the center

(0, - 3)

along the y-axis

(0, - 3 + p)

= (0, - 3 + (- \frac{1}{8}))
