foci 3x^2-9x

Solution

foci

3 x^{2} - 9 x

Solution

(\frac{3}{2}, - \frac{20}{3})

Solution steps

Rewrite

y = 3 x^{2} - 9 x

in the standard form

4 \cdot \frac{1}{12} (y - (- \frac{27}{4})) = (x - \frac{3}{2})^{2}

(h, k) = (\frac{3}{2}, - \frac{27}{4}), p = \frac{1}{12}

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

p

from the center

(\frac{3}{2}, - \frac{27}{4})

along the y-axis

(\frac{3}{2}, - \frac{27}{4} + p)

= (\frac{3}{2}, - \frac{27}{4} + \frac{1}{12})

Refine

(\frac{3}{2}, - \frac{20}{3})

Popular Examples

foci 9-x^2 foci

9 - x^{2}

foci+(5x-1)^2 foci

+ (5 x - 1)^{2}

foci y=x^2+2x+12 foci

y = x^{2} + 2 x + 12

foci x=(y+4)^2 foci

x = (y + 4)^{2}

foci y=6x^2-1 foci

y = 6 x^{2} - 1
