foci y=4+2x-x^2

Solution

foci

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

Solution

(1, \frac{19}{4})

Solution steps

Rewrite

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

in the standard form

4 (- \frac{1}{4}) (y - 5) = (x - 1)^{2}

(h, k) = (1, 5), p = - \frac{1}{4}

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

p

from the center

(1, 5)

along the y-axis

(1, 5 + p)

= (1, 5 + (- \frac{1}{4}))

Refine

(1, \frac{19}{4})

Popular Examples

foci x^2-4x+8 foci

x^{2} - 4 x + 8

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
