foci x^2+3x-1

Solution

foci

x^{2} + 3 x - 1

Solution

(- \frac{3}{2}, - 3)

Solution steps

Rewrite

y = x^{2} + 3 x - 1

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{13}{4})) = (x - (- \frac{3}{2}))^{2}

(h, k) = (- \frac{3}{2}, - \frac{13}{4}), p = \frac{1}{4}

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

p

from the center

(- \frac{3}{2}, - \frac{13}{4})

along the y-axis

(- \frac{3}{2}, - \frac{13}{4} + p)

= (- \frac{3}{2}, - \frac{13}{4} + \frac{1}{4})

Refine

(- \frac{3}{2}, - 3)

Popular Examples

foci y=-10x^2 foci

y = - 10 x^{2}

foci (y+1)^2+3 foci

(y + 1)^{2} + 3

foci (x-5)^2=16(y+3)foci

(x - 5)^{2} = 16 (y + 3)

foci y=28x^2+47x+15 foci

y = 28 x^{2} + 47 x + 15

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

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