foci x^2-4x-12

Solution

foci

x^{2} - 4 x - 12

Solution

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

Solution steps

Rewrite

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

in the standard form

4 \cdot \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+18500(0.09-x^2)foci

+ 18500 (0.09 - x^{2})

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

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

foci y=x^2+10x+25 foci

y = x^{2} + 10 x + 25

foci (x+2)^2=8(y-3)foci

(x + 2)^{2} = 8 (y - 3)

foci x^2+2x-12y+37=0 foci

x^{2} + 2 x - 12 y + 37 = 0
