**MathMate**, Friday, September 24, 2010 at 8:36pmThe composite of functions g(x)=sin(x) and h(x)=x²-x+1 can be represented by ("g" of "h")

g o h(x)

=g( h(x) )

=sin( h(x) )

=sin(x²-x+1)

The domain is limited by h(x) and g(x).

Since the domain of both h(x) and g(x) is ℝ, the domain of g o h(x) is also ℝ.

I will leave it to you to find the range.
