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.

Did I do these probelms correctly? Find the intercepts 1. y^2 = x^2 - 4x y^2 = x(x - 4) Y intercepts y^2 = 0(0 - 4) (0,0) x intercepts 0 = x(x - 4) 0 = x - 4 4 = x (4,0) 2. y = (x (x + 3))/(3x + 1)^2 y intercetps y = (0(0 + 3))/(3(0)
