foci x^2+4x-3

Solution

foci

x^{2} + 4 x - 3

Solution

(- 2, - \frac{27}{4})

Solution steps

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - (- 7)) = (x - (- 2))^{2}

(h, k) = (- 2, - 7), p = \frac{1}{4}

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

p

from the center

(- 2, - 7)

along the y-axis

(- 2, - 7 + p)

= (- 2, - 7 + \frac{1}{4})

Refine

(- 2, - \frac{27}{4})

Popular Examples

foci (y-4)^2=-8(x-1)foci

(y - 4)^{2} = - 8 (x - 1)

foci (y-1)^2=16(x+3)foci

(y - 1)^{2} = 16 (x + 3)

foci y=-3x^2+12x-8 foci

y = - 3 x^{2} + 12 x - 8

8 x^{2}

foci x^2+3x-5 foci

x^{2} + 3 x - 5
