foki y=3x^2-7

Lösung

foki

y = 3 x^{2} - 7

Lösung

(0, - \frac{83}{12})

Schritte zur Lösung

Rewrite

y = 3 x^{2} - 7

in the standard form:

4 \cdot \frac{1}{12} (y - (- 7)) = (x - 0)^{2}

(h, k) = (0, - 7), p = \frac{1}{12}

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

p

from the center

(0, - 7)

along the y-axis

(0, - 7 + p)

= (0, - 7 + \frac{1}{12})

Fasse zusammen
