foci 12+4x-x^2

Solution

foci

12 + 4 x - x^{2}

Solution

(2, \frac{63}{4})

Solution steps

Rewrite

y = 12 + 4 x - x^{2}

in the standard form

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

(h, k) = (2, 16), p = - \frac{1}{4}

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

p

from the center

(2, 16)

along the y-axis

(2, 16 + p)

= (2, 16 + (- \frac{1}{4}))

Refine

(2, \frac{63}{4})

Popular Examples

foci y=2x^2-5x+5 foci

y = 2 x^{2} - 5 x + 5

foci 5x^2+30x+24y=51 foci

5 x^{2} + 30 x + 24 y = 51

foci x^2+8y=0 foci

x^{2} + 8 y = 0

foci y^2+6y+2x+1=0 foci

y^{2} + 6 y + 2 x + 1 = 0

foci (y+5)^2=-16(x-3)foci

(y + 5)^{2} = - 16 (x - 3)
