foki y=3x^2-30x+77

Lösung

foki

y = 3 x^{2} - 30 x + 77

Lösung

(5, \frac{25}{12})

Schritte zur Lösung

Rewrite

y = 3 x^{2} - 30 x + 77

in the standard form

4 \cdot \frac{1}{12} (y - 2) = (x - 5)^{2}

(h, k) = (5, 2), p = \frac{1}{12}

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

p

from the center

(5, 2)

along the y-axis

(5, 2 + p)

= (5, 2 + \frac{1}{12})
