foci x^2-4x+8

Solution

foci

x^{2} - 4 x + 8

Solution

(2, \frac{17}{4})

Solution steps

Rewrite

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

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{17}{4})

Popular Examples

foci x^2-4x+1 foci

x^{2} - 4 x + 1

foci x=y^2-y-42 foci

x = y^{2} - y - 42

foci y=-0.1(x+12.58)^2+6.37 foci

y = - 0.1 (x + 12.58)^{2} + 6.37

foci 8x^2+1 foci

8 x^{2} + 1

foci y=-2x^2-3 foci

y = - 2 x^{2} - 3
