foci y=2x^2-9

Solution

foci

y = 2 x^{2} - 9

Solution

(0, - \frac{71}{8})

Solution steps

Rewrite

y = 2 x^{2} - 9

in the standard form:

4 \cdot \frac{1}{8} (y - (- 9)) = (x - 0)^{2}

(h, k) = (0, - 9), p = \frac{1}{8}

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}{8})

Refine

(0, - \frac{71}{8})

Popular Examples

y = 2 x^{2} - 3

foci y=x^2+8x+18 foci

y = x^{2} + 8 x + 18

foci 5x^2+6x-4 foci

5 x^{2} + 6 x - 4

foci y=3x^2-x-4 foci

y = 3 x^{2} - x - 4

foci y=x^2-2x-9 foci

y = x^{2} - 2 x - 9
