Lsit the intercepts and test for symmetry.
y^2  x  4 = 0
I got (4,0) and (0,2) for the intercepts.
y^2  x  4 = 0 Is not symmetrical to the x axis, correct?
y^2(x)  4 = 0 Is not symmetrical to the y axis, correct?
y^2 + x  4 = 0 Is not symmetrical to the origin, correct?

I solved it under your 3:35pm posting.
