foci x(2x+3)

Solution

foci

x (2 x + 3)

Solution

(- \frac{3}{4}, - 1)

Solution steps

Rewrite

y = x (2 x + 3)

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{9}{8})) = (x - (- \frac{3}{4}))^{2}

(h, k) = (- \frac{3}{4}, - \frac{9}{8}), p = \frac{1}{8}

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

p

from the center

(- \frac{3}{4}, - \frac{9}{8})

along the y-axis

(- \frac{3}{4}, - \frac{9}{8} + p)

= (- \frac{3}{4}, - \frac{9}{8} + \frac{1}{8})

Refine

(- \frac{3}{4}, - 1)

6 x^{2} - 49

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

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

foci (x-3)^2=-4(y-1)foci

(x - 3)^{2} = - 4 (y - 1)

foci-(x-1)^2 foci

- (x - 1)^{2}

foci-x^2+6x-9 foci

- x^{2} + 6 x - 9
