  1. the domain is the set of real numbers
    Since there are no operators such as square roots and no variable denominators, and knowing the general shape of a cube, we can see that the range
    must also be the set of real numbers.

    If f(x)=sin(x) and g(x)=x^2-x+1, find the domain of f(g(x)) and g(f(x)). I was able to determine that: f(g(x))= sin(x^2-x+1) and g(f(x))= sin(x)^2 -sin(x) +1 Here is what I am thinking: the range of f(x) is (x e R) and the range
