f(x)=x^3-x^2+4 and g(x)=x^2-1 find: -the domain of (f/g)(x) -f(g(x)) thanks!! also what does the x have to do with finding the answers when they tell you to find (f/g)(x) ??

thank you! but what would the domain be in interval notation?
g(x) is equal to 0 for x=-1 or x=1 Therefore the domain of f/g is ]-oo,-1[ U ]-1,1[ U ]1,+oo[
