foci-x^2+4x+5

Solution

foci

- x^{2} + 4 x + 5

Solution

(2, \frac{35}{4})

Solution steps

Rewrite

y = - x^{2} + 4 x + 5

in the standard form

4 (- \frac{1}{4}) (y - 9) = (x - 2)^{2}

(h, k) = (2, 9), p = - \frac{1}{4}

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

p

from the center

(2, 9)

along the y-axis

(2, 9 + p)

= (2, 9 + (- \frac{1}{4}))

Refine

(2, \frac{35}{4})

Popular Examples

foci x=-3y^2 foci

x = - 3 y^{2}

foci (y-7)^2=-12(x+1)foci

(y - 7)^{2} = - 12 (x + 1)

foci x^2-6x-12y+21=0 foci

x^{2} - 6 x - 12 y + 21 = 0

foci x^2-15x foci

x^{2} - 15 x

foci 2(x+1)^2 foci

2 (x + 1)^{2}
