foki y=2x^2-39

Lösung

foki

y = 2 x^{2} - 39

Lösung

(0, - \frac{311}{8})

Schritte zur Lösung

Rewrite

y = 2 x^{2} - 39

in the standard form:

4 \cdot \frac{1}{8} (y - (- 39)) = (x - 0)^{2}

(h, k) = (0, - 39), p = \frac{1}{8}

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

p

from the center

(0, - 39)

along the y-axis

(0, - 39 + p)

= (0, - 39 + \frac{1}{8})

Fasse zusammen
