Solution for y=7/2x^2 equation: 


x in (-oo:+oo)

y = (7/2)*x^2 // - (7/2)*x^2

y-((7/2)*x^2) = 0

(-7/2)*x^2+y = 0

-7/2*x^2 = -y // : -7/2

x^2 = 2/7*y

x^2 = 2/7*y // ^ 1/2

abs(x) = (2/7)^(1/2)*y^(1/2)

x = (2/7)^(1/2)*y^(1/2) or x = -((2/7)^(1/2)*y^(1/2))

x in { (2/7)^(1/2)*y^(1/2), -((2/7)^(1/2)*y^(1/2)) }
