foki y=4x^2-9

Lösung

foki

y = 4 x^{2} - 9

Lösung

(0, - \frac{143}{16})

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 9

in the standard form:

4 \cdot \frac{1}{16} (y - (- 9)) = (x - 0)^{2}

(h, k) = (0, - 9), p = \frac{1}{16}

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

p

from the center

(0, - 9)

along the y-axis

(0, - 9 + p)

= (0, - 9 + \frac{1}{16})
