Solution for Y=2/3x2+1 equation: 


x in (-oo:+oo)

Y = (2/3)*x^2+1 // - (2/3)*x^2+1

Y-((2/3)*x^2)-1 = 0

Y+(-2/3)*x^2-1 = 0

-2/3*x^2 = -(Y-1) // : -2/3

x^2 = -3/2*(1-Y)

x^2 = -3/2*(1-Y) // ^ 1/2

abs(x) = (-3/2)^(1/2)*(1-Y)^(1/2)

x = (-3/2)^(1/2)*(1-Y)^(1/2) or x = -((-3/2)^(1/2)*(1-Y)^(1/2))

x in { (-3/2)^(1/2)*(1-Y)^(1/2), -((-3/2)^(1/2)*(1-Y)^(1/2)) }
