the only easy way to solve this problem is to try plot the curve of both the plots, and see where they intersects, from the curve it can be seen the solution are , 0, .6, and 1.

f(x)=(x^3+1)/2 and g(x)=(v2x-1)^(1/3) are inverse functions of each other
f(x)=g(x) has a solution when f(x)=X BECAUSE IF THEY INTERSECT they intersect on y=x
so we can have the roots for (x^3+1)/2=x as x= 1 and (-1+-root5)/2
