foci y=x(x-4)

Solution

foci

y = x (x - 4)

Solution

(2, - \frac{15}{4})

Solution steps

Rewrite

y = x (x - 4)

in the standard form

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

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

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

p

from the center

(2, - 4)

along the y-axis

(2, - 4 + p)

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

Refine

(2, - \frac{15}{4})

Popular Examples

foci x+y^2=0 foci

x + y^{2} = 0

foci 2x^2+9x-56 foci

2 x^{2} + 9 x - 56

z^{2}

foci (x-5)^2=12(y-3)foci

(x - 5)^{2} = 12 (y - 3)

foci x^2-6x-5y-1=0 foci

x^{2} - 6 x - 5 y - 1 = 0
