foki y=5x^2+6x-7

Lösung

foki

y = 5 x^{2} + 6 x - 7

Lösung

(- \frac{3}{5}, - \frac{35}{4})

Schritte zur Lösung

Rewrite

y = 5 x^{2} + 6 x - 7

in the standard form

4 \cdot \frac{1}{20} (y - (- \frac{44}{5})) = (x - (- \frac{3}{5}))^{2}

(h, k) = (- \frac{3}{5}, - \frac{44}{5}), p = \frac{1}{20}

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

p

from the center

(- \frac{3}{5}, - \frac{44}{5})

along the y-axis

(- \frac{3}{5}, - \frac{44}{5} + p)

= (- \frac{3}{5}, - \frac{44}{5} + \frac{1}{20})
