The differential equation of all parabola having their axis of symmetry coinciding with axis of x is

A

yy2 + y12 = 0

B

xd2xdy2\frac{d^{2}x}{dy^{2}} + (y1)2 = 0

C

yy2 + y1 = 0

D

None of these

Answer

yy2 + y12 = 0

Explanation

Solution

The equation of such parabola

y2 = 4a(x – h).

only two parameters a and h, eliminate these
