foki-30x^2+28x-6

Lösung

foki

- 30 x^{2} + 28 x - 6

Lösung

(\frac{7}{15}, \frac{21}{40})

Schritte zur Lösung

Rewrite

y = - 30 x^{2} + 28 x - 6

in the standard form

4 (- \frac{1}{120}) (y - \frac{8}{15}) = (x - \frac{7}{15})^{2}

(h, k) = (\frac{7}{15}, \frac{8}{15}), p = - \frac{1}{120}

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

p

from the center

(\frac{7}{15}, \frac{8}{15})

along the y-axis

(\frac{7}{15}, \frac{8}{15} + p)

= (\frac{7}{15}, \frac{8}{15} + (- \frac{1}{120}))
