foci 0.5x^2-2x-2

Solution

foci

0.5 x^{2} - 2 x - 2

Solution

(2, - 3.5)

Solution steps

Rewrite

y = 0.5 x^{2} - 2 x - 2

in the standard form

4 \cdot 0.5 (y - (- 4)) = (x - 2)^{2}

(h, k) = (2, - 4), p = 0.5

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

p

from the center

(2, - 4)

along the y-axis

(2, - 4 + p)

= (2, - 4 + 0.5)

Refine

(2, - 3.5)

Popular Examples

foci y=2x^2-39 foci

y = 2 x^{2} - 39

foci y^2+6y+8x+25=0 foci

y^{2} + 6 y + 8 x + 25 = 0

foci (x^5+x^4+x^3+x^2+x+1)/(x^3+1)foci

\frac{x ^{5} + x ^{4} + x ^{3} + x ^{2} + x + 1}{x ^{3} + 1}

foci y^2-12y+4x+4=0 foci

y^{2} - 12 y + 4 x + 4 = 0

foci x^2=-20y foci

x^{2} = - 20 y
