foci 4x^2+8x

Solution

foci

4 x^{2} + 8 x

Solution

(- 1, - \frac{63}{16})

Solution steps

Rewrite

y = 4 x^{2} + 8 x

in the standard form

4 \cdot \frac{1}{16} (y - (- 4)) = (x - (- 1))^{2}

(h, k) = (- 1, - 4), p = \frac{1}{16}

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

p

from the center

(- 1, - 4)

along the y-axis

(- 1, - 4 + p)

= (- 1, - 4 + \frac{1}{16})

Refine

(- 1, - \frac{63}{16})

foci (4x^3-7x^2-11x+5)/(4x+5)foci

\frac{4 x ^{3} - 7 x ^{2} - 11 x + 5}{4 x + 5}

foci y=3x^2-5x foci

y = 3 x^{2} - 5 x

foci 2x^2-12x+14-14y=0 foci

2 x^{2} - 12 x + 14 - 14 y = 0
