foki 4x^2-24x-30

Lösung

foki

4 x^{2} - 24 x - 30

Lösung

(3, - \frac{1055}{16})

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 24 x - 30

in the standard form

4 \cdot \frac{1}{16} (y - (- 66)) = (x - 3)^{2}

(h, k) = (3, - 66), p = \frac{1}{16}

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

p

from the center

(3, - 66)

along the y-axis

(3, - 66 + p)

= (3, - 66 + \frac{1}{16})

Fasse zusammen
