I am trying to test an equation for symmetry. The equation is x^2 = y^3 + 4. I am starting by trying to find the intercepts. I think I found the intercepts for x - (2,0), (-2,0). I am having trouble finding the intercepts for y. I substitute 0 for X and get 0 + y^3 + 4. I convert that to y^3 = -4. I...
