The domain of f(x)f(x) is x<=1x1

Explanation:

As the range for sin(x)sin(x) is [-1,1][1,1] for all real xx

So, if we simplify the above equation:

f(x)=arcsin(sqrt(x))f(x)=arcsin(x) ;or
sin(f(x))=sqrt(x)sin(f(x))=x ;or
So, we know that the range of above equation is [-1,1][1,1]
thus, sqrt(x)x is [-1,1][1,1] ;or
x<=1x1 is the solution or the domain of the original f(x)f(x)
