foci-2x^2+6x

Solution

foci

- 2 x^{2} + 6 x

Solution

(\frac{3}{2}, \frac{35}{8})

Solution steps

Rewrite

y = - 2 x^{2} + 6 x

in the standard form

4 (- \frac{1}{8}) (y - \frac{9}{2}) = (x - \frac{3}{2})^{2}

(h, k) = (\frac{3}{2}, \frac{9}{2}), p = - \frac{1}{8}

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

p

from the center

(\frac{3}{2}, \frac{9}{2})

along the y-axis

(\frac{3}{2}, \frac{9}{2} + p)

= (\frac{3}{2}, \frac{9}{2} + (- \frac{1}{8}))

Refine

(\frac{3}{2}, \frac{35}{8})

Popular Examples

foci y=x^2+2x+1 foci

y = x^{2} + 2 x + 1

foci x=3(y-2)^2-7 foci

x = 3 (y - 2)^{2} - 7

foci 3x^2+2x+6 foci

3 x^{2} + 2 x + 6

foci 1/8 x^2-y=0 foci

\frac{1}{8} x^{2} - y = 0

foci-x^2+4y-44=-8x foci

- x^{2} + 4 y - 44 = - 8 x
