foci 5x^2+4

Solution

foci

5 x^{2} + 4

Solution

(0, \frac{81}{20})

Solution steps

Rewrite

y = 5 x^{2} + 4

in the standard form:

4 \cdot \frac{1}{20} (y - 4) = (x - 0)^{2}

(h, k) = (0, 4), p = \frac{1}{20}

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

p

from the center

(0, 4)

along the y-axis

(0, 4 + p)

= (0, 4 + \frac{1}{20})

Refine

(0, \frac{81}{20})
